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.

OS = Windows 7 Pro. Web-browser = Firefox. Both worked very well for many years on desktop PC and laptop. Recently desktop PC repeatedly reported "Windows Explorer has stopped" whenever Firefox was started. Today I updated Firefox on my laptop after several weeks of non-use. "Windows Explorer has stopped" appeared immediately Firefox started - error never seen before on the laptop. Could the most recent update to Firefox be the cause of this fault?

Deleting autofill entries does not work per article. The info is still there. Clearing history does not work either. Do I need to restart computer for it to forget/delete entries? Thank you. Fred couvrette

After Firefox update 115.2.0esr (20230821110938) was installed on 9/8, I could not properly access my online banking accounts. Installation of Firefox update 115.2.1esr (20230912014149) on 9/16 did not resolve the issue. Can these two updates be uninstalled? I was still able to access my online banking accounts after Firefox update 115.1.0esr (20230724124053) was installed on 8/8. I want to revert back to that point to see if this will resolve the issue.

Thank you!

'Block Site' merely blocks access to a list of sites, but does not stop them appearing. is there a way to stop websites which use <gob.mx> in the address, which attempt to re-direct to 'mirror' sites that try to steal personal info and generate 'Illegal re-direct' warnings from anti-virus programs from appearing in firefox searches, automatically, rather than having to enter <XXXXXXX, -gob.mx> each time I search ?

I upgraded from 67(?) to 115.2.1esr 32 bit and all the tabs were lost after the restart, ok, i understaqnd that. But when i went into settings the "Open previous windows and tabs" is dimmed and cant be set on

really like this ability but cant set the faint option, Watch do I need to do? FF has been my only browser for 18 or so years - please help

Is it true that I can no longer go to my Kroger.com using Firefox? This is what their technical lady, Jessie, told me. I have trouble signing in every week with Firefox. This week it is a "no go" at all.

How do I fix this? I like to use Google for my searches and Yahoo takes over every time. I can switch it, but it's such a nuisance and time-waster to have to keep switching it back to Google. What can I do?

Ever since the Firefox 115.2.0esr came out, all searches — not just Google but any sites that have a search box — freeze the page for nearly 10 full seconds before it initiates the search. I tried disabling my antivirus just to be sure an update to that isn't messing with things and it's not. This is definitely a Firefox issue and a VERY annoying one. I can't believe an emergency patch hasn't already been released!

When you cancel a program, you cannot start another one because Firefox is not responding and first the"old" Firefox must be stopped. This is onerous. Why not automatically (i.e. with a software delete) stop the "old" Firefox each time a Firefox-supported program is cancelled?

Dear Support,

I am unable to access my website, both to view and to work on it as an admin in WP.

This is negatively impacting my business, leaving me quite concerned, and hope you can please help a.s.a.p. as other browsers seem to work fine.

Thank you.

Hello, i need to enable and disable for privacy reasons, the setting "media.peerconnection.enabled" (aka WebRTC) via GUI to avoid to go everytime into about:config settings, search for the string, and double click it to disable or enable.

If is fleasible i prefer to add a custom icon in the customization tools bar windows, so i can drag it and move into the upper part of firefox freely (for example i would like to have it above url bar in the left corner, above the 3 lines application menù.

Thanks in advance if someone can help me.
