Firefox Support Forum

When copying text from a website in one Firefox window, and pasting in a separate Fire Fox window, formatting issues occur

• Running on Windows 10
• Firefox, windows/tabs not in container
• Pasting text from Coursera to Notion.so fails to start text on current line and properly format.
• Works on Microsoft Edge with no issue, so problem is isolated to Firefox

Attaching images for clarification and comparison. (sorry for quality, quick MS.paint job)

• after further testing, it appears that copying from Coursera in Firefox to Microsoft Edge also has the same formatting issue, so it seems to be a compatibility situation between Firefox copying from Coursera specifically, and not an issue with pasting to Notion.so

• appreciate the fact that there are multiple third party factors at play, but the issue is killing my productivity so any help is appreciated!

Is it possible to spell check the entire web page using both Hunspell built-in dictionaries and user-defined dictionaries *.dic, already prepared text in Firefox. As it is done in text editors like Libre Office (also uses Hunspell) but for web site, checking the text from top to bottom with errors in a separate window, so spell check is not only in the text input/search field.

How does the translator determine when it is activated? Does the translator give the ability to translate selected text, or just the visited page?

I was trying to find a site to test it. I found this.

Spanish Proficiency Test

Maybe it's not an ideal example, but it neither translates the page, or gives the option to translate selected text.

So the whole issue started when I couldn't share a video on my community tab because it kept giving me the error message "enable google.com for cookies". I click accept a few times it didn't work. Then I went to cookies- extensions and enabled both youtube and google in it, didn't work. I deleted my cookies and data and tried again. I had to sign up to all my google accounts. Still it didn't fix the issue I kept getting the same error. Then I went to the enhanced cookies settings went to customs and chose the option "cookies from unvisited sites" This fixed the community tab issue. I shared my video and then went back to settings and set the standard enhanced tracking protection. I got signed off my gmail and google accounts I signed up again and closed the browser.

When I came back my google and gmails are signed out again but my accounts still signed in my youtube for some reason. I keep getting signed off on google but not youtube. I don't have the "Delete cookies and site data when Firefox is closed" option enabled. IT IS DISABLED.

HOW DO IT FIX IT? I don't want to keep signing in every time also I don't wish to reinstall firefox. PLEASE HELP

My firefox has jumped back to an earlier setting and I cannot get it back to latest computer did an update and that's when it went wrong also get message cannot load xpcom Help.

Hi,

My Firefox keeps crashing every time I copy and past something from Excel and try to go to Firefox, it immediately goes gray and the only option that works is restarting it and waiting does nothing (which means I constantly relog back into to all of my accounts that I am using for job searches). It has been many weeks since this started happening and auto updates have not corrected anything. I've submitted the crash reports just now. Let me know what can fix this. Thanks!

Hello everybody,

I own a website, let's say "website.com"

I transferred it from one host provider to another. "website.com" is now hosted by the new host provider, I know the transfer is now finished.

But when I browse the website and go to the URL website.com, I have this error message:

Warning: probable security risk Firefox has detected a potential security threat and has not proceeded towards If you access this site, attackers could steal information such as passwords, e-mails or credit card details. To find out more... Back (recommended) Advanced...

1/ Is it an SSL certificate error message?

2/ Should I solve this issue with my new host provider? What should I ask them?

Thanks a lot,

After installing the latest update on my dell PC, firefox came up with a blank screen that would not allow search or even close. I had to use task manager to close and then uninstall. Note sure it's going to work.

Whenever I try to watch a video or stream (any site) I can watch the video just fine as long as the audio is muted. However, when I unmute the idea, the video pretty much stops (can stutter a little bit) and the audio plays a roughly 5 second loop of when it was unmuted. This happens on all sites, all formats of videos.

'I refreshed my Firefox bn, I had saved asswords which I could see, I don't want to l;ose book msrks and passwords , refresh didn't helput it still won' t

Hello there,

So I have this issue where the tabs I left opened on my PC are not showing up, only the ones from 3 days ago (even though I used it yesterday)

Before, sync would, I assume, work automatically when Firefox is closed or something like that, which isn't the case anymore for me, for the last few days/weeks..

So I'm wondering, what can I do to make it work like before?

Thanks in advance!

After a recent Firefox update, there was no "restore" option. When I take the steps to restore the last session, the option is greyed-out. Luckily there is a decent-sized file named sessionstore.jsnlz4 in the folder from a few weeks ago, so I followed the instructions here to restore that file. BUT, even with that file placed back inito the appropriate folder, I still never get the option to "restore". I feel pretty sure that the file (1.18 MB) has inside what I need/want, but how can I get Firefox to "restore" using that file?

Hi, I am running Windows 10 on PC and my Firefox browser keeps crashing for no apparent reason. I only had a translate extension but since turning that off it still does it. Yesterday (02/10/2023 - 23:45) I got an error pop up "minidump-analyser.exe - Application Error. The exception Breakpoint. A breakpoint has been reached. (0x80000003) occured in the application at location 0x00007FFE7200276E. Click OK to terminate this program." Today (03/10/2023 16:06) after less than an hour from switch on I got another error pop up "SwUSB.exe - System Error. A new guard page for the stack cannot be created." I thought I was reasonably tech savvy but I'm am baffled by this. Please can anyone help?

About three days ago, the dropdown lists for various websites I use stopped populating unless I use the backspace. So, for instance, if I want to find "John", nothing happens if I just start to type it in. But if I type in "Jo" and then backspace, John pops up. (Perhaps important: Even though I have now deleted the "o", only John pops up, not names beginning with J but followed by a different letter.) Curiously, it seems like the first time each day that I go onto any given website, the dropdown does populate properly, but just that once. I checked Edge and Chrome, and the dropdowns work fine there, so it's definitely a Firefox problem. Any ideas about what is going on and how I can fix it? Thanks.

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.
