I'm using Windows 7 and have been migrated to the esr updates for Firefox. I think this problem started cropping up just before going to the esr versions, but not sure. Firefox will a) randomly hang and do nothing for 5-10 minutes and then pick up fine b) tends to hang a lot when signing into websites like banks, etc, doing the same thing as (a). I've updated FF several times since then, but same problem. I did try to do 1 fix which suggested creating a new "places" database, but that did not solve the problem. Not sure where to go from here as nothing has changed on my computer since the problem started - no new software, etc.

Many bugs and crashes with Firefox

1. 1 Not able to install an automatic update, via the Menu Help --> About Firefox (or Thunderbird). This bug / problems sits already inside the earlier versions of Firefox and Thunderbird.

• A No new version is shown.
• B Firefox (or Thunderbird) tries to download / install this update, bug become someway corrupted and also stuck in this process.
• C Firefox (or Thunderbird) says to apply the update you must restart the program. After Firefox (or Thunderbird) was restarted, the program keeps trying installing or downloading this same or another update. I see a spinning circle only, no progress bar. Waiting, trying again later or another restart from Firefox (or Thunderbird) does nothing.

Only way to update Firefox is via https://www.mozilla.org/en-US/firefox/all/#product-desktop-release Which always shows the wrong language. Only way to update Thunderbird is via https://www.thunderbird.net/en-US/thunderbird/all/#product-desktop-release Here, I can click on letter from my language and download the setup package. After this update installation was done, the Help --> About (program name) window show the program is last version. But not seems not always the last version, like version x.x.01 to x.x.02, then tries to install this newer small version and gets stuck in the same loop or corruption.

• D You must use the setup package, because the installer doesn't work, likes to abort the installation and shows error messages about something gone wrong. Installer package is incomplete or damaged, not for current version and Windows.
• E For last newer versions, they seems not working anymore directly. The program can be restarted once or few times before it seems working. Until other bugs appear.
• F Always adding a new and faulty shortcut, but I have already a working shortcut on my Desktop. Icon hasn't logo from Firefox or Thunderbird, but the setup icon.
• G Sometimes you cannot start Firefox or Thunderbird, due the update did something wrong.

Missing file(s) and/or some strange error message after I clicked on the shortcut from the program. Another run from this "update" setup is needed. Remove a or all "Firefox.exe" from the Taskmanager list.

• H Bug that stops add-ones working. This can be happen due the general function / thing for add-ones inside Firefox crashes, become bugged or corrupted. 1 add-one or more add-ones take the others and stop working, become bugged or corrupted. Add-ones will forget things, their work / functions or do it halfway. Has something to do with the installation and/or data from add-ones. They seems to not having support or do anything about their problems.

1. 2 Random many crashes without any useful (error) messages, can be with closing the program itself.

Already from earlier versions of Firefox. And also Thunderbird too. This bug seems to sit deep inside the programs. I should be to use Firefox, Thunderbird, Notepad together, with having a some folders open. Switching between them can be annoying slow. Takes longer time be before responding. I'm seeing empty white or black windows. Only last selected section is visible, has the text and smaller pictures. I can have Firefox and Thunderbird left open for hours and later finding one or both programs are closed by itself. No reason, no permission given to do that. Add a new tab or click on a current site, there is no (fast) respond. Same for buttons, filters and filling in forms on a site. One program can pull the other program in closing to when the one is crashing. Also Windows will show several error messages about programs are using to much memory and must be closed. If this has programs listed, then Firefox seems to appear most here of the programs I'm using.

Updating doesn't fix anything Using the safe mode and new profiles are no long time solutions, every time anything is gone or nog working better.

It seems you must have 2 profiles running at same time when you want read something and not switching back between every minute or so. If 1 is near crashing, you have still the other one running.

1. 3 Why I'm seeing 20x to 72x a Firefox.exe in my Taskmanager? They takes a lot of memory, showing different sizes. I started Firefox once. This is not needed.

1. 4 Some sites seems to not work in Firefox or takes longer time.

Same for responding on clicking, using filters, buttons and sending forms. Clicking on those (annoying) accept (popup) windows. Unable to login or confirm an (security) action like this with a word or number given via e-mail. Might be something for the site. When you need to use Private Browsing for this.

1. 5 Icons from installed add-ones don't appear in main bar, at right side. How to use them? Before they did.

1. 6 Site using third party host sites are slow and mostly don't work. Connection errors.

"Seems fine here, but something with you". Refresh page doesn't fix it. Wait and try again later, how long? Firefox should block these sites.

1. 7 After updating to Firefox version 115.0.2 and continue my last session, there are appear several new bugs.

• A I cannot longer visit sites. Even earlier visited sites don't load. Firefox keeps stuck in loading or receiving site info data. Sites don't appear, just an empty (white) page. Also about:support doesn't work. Strangely, I can visit Google.com but not open any site from there. I tried Private Browsing, so no add-one can do something with this.

I had Firefox running for some hours, these sites are still stuck in "loading" or something else.

• B Right click to open a site or page in a new tab doesn't longer work. Right click menu appears, but action will not be done. Which can be strange at top, missing or changed items.

• C Same to copy line of text or picture, action isn't longer "remembered".

Now, I created again a new profile and again this doesn't fix them. Even more bugs and stranger. Again lost everything, settings, sites, installing dictionaries and add-ones. Stupid.

• C1 I can visit websites, but with some strange things, not always working fine.

That makes it to post my problems here.

• C2 Cannot longer type keywords in the addressbar and after pressing Enter, you should visit Google with search results. Firefox thinks the given keyword is a not existing website.

In Settings (via about:preferences#search), there are no search engines (Google, Wikipedia, ect) in the list, who should be there by default. Also there's no default search engine selected, the list therefor is small and empty.

• C3 Yet visited near 10 sites, who I cannot visit any of the sites with my other long time using profile. Then Firefox crashed by random, white empty window. Windows adds not responding at end of the program's title bar. I could restart Firefox after that, get the "continue after a crash" tab and revisit any of these sites in their opened tabs.

• C4 A site keeps saying cookies are disabled / denied, while minimal are accepted when some of that stupid (popup) windows did show. This means: Some stupid messages don't disappear after clicking "OK", the "X" or close buttons / links. Site might not work fine or on some parts. Something can follow you browsing through the site. Not able to visit that site or part.

• C5 A site keeps saying there is an ad-blocker installed, but there is no add-one like that installed. This means: Stupid messages like these keep appearing; site cannot work fine; you cannot visit the site due some invisible wall or blocking thing. Some can follow you browsing through the site. This is very annoying.

• C6 With one profile I cannot longer open sites who worked before. Keeps loading, shows URL in addressbar and on the tab.

And the about: .... pages. While with a new profile I can visit those sites, but right click menu is bugged.

• Cannot open site or page in new tab. Only on Google based sites are working for unknown reasons, but not YouTube.
• Missing items or I can see more gray things and lines.
• Cannot copy selected text. Stil having old or wrong text.
• Cannot Search with Google, this option is missing.
• Cannot see the source code from the page, due action is not happen.
• On sites that are working you can only read that current content. Can open links in new tabs, but their pages are empty / white, keep loading forever.
• A few sites don't load and still giving a empty page. Loading takes longer then needed. For same site.
• Use Google by typing the keyword in the addressbar doesn't visit Google site, but Firefox thinks the site doesn't exist, is wrong typed. You must go to Google.com and typing the keyword in the textbox here.
• If a site worked first, then later it cannot working longer, keeps stuck in loading and showing a empty white page / tab.
• Login for some sites is not longer possible, email send with security word or number doesn't appear. I can send myself a test e-mail to this e-mail address. Waited the time enough and made a new attempt, still the same.

Windows PC. Firefox version 117.0 x64. Via Help --> About Firefox, because about:support doesn't show the version and build.

For some time now I have been having trouble with viewing you tube video's. At times the video freezes or just sort of locks up. But, I don't have the same problem with other browsers, Chrome, Brave. So, it just seems with Firefox this issue pertains. Can some one please help so I don't experience the Firefox you tube problems. Thank you.

Very upset...FF update took some info but lost years of info (history, book marks, cookies etc) AND DOES NOT WORK!

I have updated before no problem with transfer of emails, folders, address books, settings, history, cookies etc BUT THIS LATEST UPDATE HAS LOST ME SO much information AND IT DOES NOT WORK AT ALL. Program opens but does nothing except greying out with (not responding) and closes. Done reinstall twice an with no applications running. Kindly send me 10 year old version so I can roll back to something that works. Regards Rick

Every solution which I have found for Firefox 89 "Proton" so far which moves the Tabs Bar below the Navigation Bar (AKA "address bar"), with the Menu Bar above it, does NOT move the Tabs Bar below the Bookmarks Bar. The Bookmarks Bar appears to be overwritten and blank, and occupies space below the Menu Bar, Navigation Bar, and Tabs Bar. This empty space separates the three bars which are implemented and the content of the currently-selected tab below it.

Currently, my userChrome.css file is a copy posted by Cor-el (?):

Evidently, the text editor for this website does several things to the above original text that, frankly, seem unnecessary and undesirable. The .CSS file is just an unformatted text file, so what is the problem with simply copying its contents and pasting it in to the body of this post?

Which is also to say that I do NOT have a clue as to what any line in the file is meant to do, what effect it has, why it is even in the file at all, or why it is written in the way that it is. So DO NOT tell me that I "CAN" create a Cascading Style Sheet on my own when I cannot even modify one that has been provided.

On the face of it, something is missing from the above CSS text. What change needs to be made to the above content so that the Bookmark Bar will appear between the Navigation Bar and the Tabs Bar??

Thank-you very much for your time and attention to this request for assistance.

Speed test on a freshly booted machine is 100/100Mbps ... very often after viewing a youtube video in Firefox, this Speed test can slow down to below 20Mbps which results in a poor streaming experience ... I have a 150/150 fiber connection and the modem speed test doesn't change ... nothing to do with anything downstream ... not running anything else except FF ... always running with the latest up to date version(s) ... things of note: the process count goes up when this occurs ... even if FF is restarted it doesn't resolve this issue ... only a reboot resolves the issue ... when rebooting there is always some UNKNOWN process that needs to be manually terminated before the reboot process runs.

I suspect one of the multilayered (FF appears to open multiple sessions with streaming) processes may be getting widowed and left running and not releasing resources which causes less and less bw to be available ... this appears to occur mostly if I either Fast Forward or try to click forward or backward on a stream timeline suggesting to me that the current timeline may not be closing properly ... process manager doesn't reveal any processes linked to firefox but there are numerous svchost processes which I expect may be involved

Are there other ways/tools to narrow down this issue so the Mozilla team might be able to fix this ... I use FF exclusively but this has become more and more of an annoyance.

My i7 2TB 2.6GHz 8GB laptop is unable to move beyond W7 64b pro but I have had the same experience on a W10 64b Pro machine so very skeptical that this is an OS related issue.

Ultimately if FF kept track of the PIDs it opens it should be able to force them to close if they refuse to close on their own. Kill Process tree ... or ... perhaps provide a log that is user accessible identifying opened PIDs so that a user could manually kill widow processes without having to reboot.

It loaded and played OK prior to this update.... works mighty fine on another browser, if this is not fixed I'm through with Mozilla AND you can remove my account!

Looking in task manager-: Firefox.exe 45,24K Firefox.exe 3,16K Firefox.exe 27,484K Firefox.exe 7,392K Firefox.exe 7,344K Firefox.exe 15,735K Firefox.exe 7,320K Firefox.exe 169,932K, I round it off to about 250MB

Yes I cleared the cach, I change profiles..... as said by each update about:config gets bigger and bigger.

I used to like Firefox because it let me set my browser up in an intuitive and comfortable way, and it was able to easily do the things I wanted to do. Then simple and useful features (e.g., tabs under the address bar) were hidden in about:config. Then they were removed completely, and you had to use third-party extensions to restore them (e.g., getting the refresh button on the address bar). Then, the third-party extensions were blocked so that you had to copy and paste third-party code into userChrome.css (e.g., restoring "View Image").

I hate updating Firefox, because it gets worse every time. This browser has turned to absolute garbage, and it just keeps circling the drain. Wasn't Firefox supposed to be the customizable browser? Mozilla seems to have decided that customization needs to be completely wiped out, and features need to be removed for...some reason?

Why is this happening? I shouldn't have to be afraid of the update button, but it's become a "make Firefox even worse" button. My only consolation now is that Mozilla won't have any more major updates for my operating system, so I might be okay for a few months.

Hello FF community. I come here for a question, maybe a confirmation (I'm gonna try to be as short as possible ).

I'm using for years infamous Aris-t2 customCSS. I'm about to "jump" from FF v88 on my desktop to V115.0.3esr. I tested everything on my laptop, and set everything on the customCSS so it looks like my actual V88. It's almost identical, but one thing is bugging me: the scrollbar.

Scrollbar on FF115 isn't the same anymore than in V88 as you can see on the screenshot I posted (test scrbr for V115, scrbr2 for V88). The clean one with "3lines grab button" I actually use is less "eye catchy" than the new one. I've made some researches, and apparently, starting FF V97 about 2 years ago, scrollbar has been change to use W10 "flat like" one, and at FF106+, every older code was apparently removed. I tried to changed a few things in about:config, like "widget.non-native-theme.enabled" or multiple commands about scrollbar, nothing changed.

So I just wanted to know if someone could confirm me that the old scroll bar I use is now impossible to get back, or if there's a command I miss that could do the thing.

Thanks, have a nice day ^^

All my search results now use google, thanks to the FORCED installation of the search engine google. Even after I have deleted it and deleted it and deleted it and deleted it and deleted it, ALL SEARCH RESULTS ARE NOW FROM GOOGLE, whether I like it or not. Mozilla has FORCED A COMPLETELY BROKEN SEARCH ENGINE ON MY PC(google), and now i can't rid of it, AND THEY ABSOLUTELY REFUSE TO HELP ANYONE.

It astounds me that there is not a dedicated article on this subject. I did an internet search - 'Infinite Scrolling Complaints'. Usability Issues Caused by Infinite Scrolling =

• • • • • • • DIFFICULTY REFINDING CONTENT *******

What kind of an engineer - in their right mind - designs a web page navigation system that

Why is there zero zilcho nada discussion about this?!? Thank you, Mozilla Firefox, for your consideration.

Firefox worked fine until the latest update 115.3esr, at time it slows to a crawl... I am now sick and tired of Mozilla and Firefox, they are about to get the boot - my style, I've used them since about version 2.

Looking in the task manager Mozilla makes it look a disgrace, at time it's hard to get a fix on some entry's because they bounce up and down.

Firefox.exe 45,24K Firefox.exe 3,16K Firefox.exe 27,484K Firefox.exe 7,392K Firefox.exe 7,344K Firefox.exe 15,735K Firefox.exe 7,320K Firefox.exe 169,932K, I round it off to about 250MB

Does these look about right? Why can't they just have one .exe? (Win 7 Pro x64)

Thanks Dave

Hi. Is there a way to customize the order of Firefox headers and footers on printed pages (including print-to-pdf)?

I prefer the header to be url only, in the center. While the footer has page on left; title in the center, and date on the right.

This used to be easy to accomplish with print options in older versions, then -- as the print dialog changed (and actually improved a lot in most *other* ways) I had to turn to about:config modifications like those described in the 1/27/21 reply here: https://support.mozilla.org/en-US/questions/1323433. But now I can't seem to find any way to have any control over print headers besides "on" and "off."

One problem I find with having both page title and url on top is that these can be long, causing one or both to be truncated.

I'm using Firefox 115.3esr.

I use an IRS web site to pay taxes. I can not get in. It says I have to use a browser with TLS1.1 or 1.2. Dose firefox use this. If not how can I get it?

Thanks Galen Alldrin

I've noticed this issue happening randomly, some of my toolbar bookmarks listed on the sidebar just up and disappear from view. As if they were never there. But I know they're still saved because when I click to Manage Bookmarks and check them there, they show up fine. The toolbar just randomly hides them for whatever reason, and I can only fix it by closing Firefox and opening it again.

I'm on the current version. I remember accessing about:support and clicking on Verify Integrity while trying troubleshoot some other issue, but don't know if that could've caused it though.
