Firefox Support Forum

I've been using Firefox for about six months. I'm a MacBook user with the most recent version of Sonoma installed. After a month or so of using Firefox it starts crashing and freezing. Sometimes I can't restart it for several minutes. Whenever this happens, I refresh it. I've refreshed it about twice. I've re-installed it twice too, but it keeps happening. Most settings are default, but I wanted to include the settings in case this could be the problem: - I've turned off Firefox home content - I've turned off all passwords and autofill features - Never Remember History - Do Not Track and Tell Websites not to share/sell my data are turned on - I left the standard-level security settings as is

I have one extension installed.

The only other browser I have installed is Safari and I am not having these issues. I should add that I don't receive any error messages when this happens, it just freezes. The most recent issue is that I was clicking on buttons on a website and it wasn't working, but when I started using the Safari browser (which also set to private mode) it worked fine.

When it works I love Firefox and would like to keep using it. I am wondering if there is anything I can do to fix this.

Hello,

I have the latest release of Firefox on windows 11.

When I try to access accesspeople.accessacloud.com, the site I use to see my work's rota, the website doesn't work and shows this message;

" 503 Service Unavailable No server is available to handle this request. "

This website works fine with Chrome, Opera, Edge, etc.

I have tried disabling all extensions, turing off tracking, as well as clearing the cookies and cache for the site and still no luck.

Please let me know if you know of any solutions.

Thanks

I cannot print from Firefox. It worked fine, and then stopped. I'm not sure what changed. It doesn't matter what printer I use. Even printing to PDF fails. No errors appear, and nothing shows up in the printer queue. All the other applications in Windows print just fine. It's just Firefox. And just for this one Windows user.

I tried clearing the saved printer settings in the about:support page. I tried refreshing Firefox. I tried uninstalling and reinstalling Firefox. I tried uninstalling, removing the mozilla folder in %appdata%, and reinstalling Firefox. No luck.

The only time I can get it to print anything is to log into a different user account on this same PC. Printing from Firefox seems to work then.

It seems there is some user-specific printer setting/file/whatever that is messed up. I'm not sure what else to try.

Thanks.

With these updates the way Firefox handles Outlook seems to get worse and worse. I don't have these problems if I switch to Edge. If I'm watching streamers on Twitch the streams pause while Outlook loads. It didn't used to do this. Something about that mail service is really hanging up the browser and it struggles more and more. There is always delay as it tries to load everything. The first email will take a while before it loads up. Sometimes if I close the tab and open a new one and try again it loads up faster. I've have all my cookies reset with this recent firefox update, everything got wiped for some reason, but getting them set up again doesn't help it. Clearing Cache hasn't helped it.

Firefox 126.0.1 Mac OS Sonoma 14.5

Everytime I select Firefox-Settings.. the Settings window opens and then crashes

This crashes with Troubleshoot mode selected

Partial crash report included below.

After rebooting a Windows 10 computer, and starting Firefox, two Firefox Windows open. The second one opens Yahoo on it's Tab with no other Tabs open. Before booting, there was only one Firefox window open. This has happened before in the past.

Could this be fixed.

I have also reported several times that at times, Bookmark folders are found missing but found in strange places where I did NOT move them. I have been told that this could be possibly caused because of my very large Bookmark file. It would be very nice if this was resolved. I have reported this at bugzilla.mozilla.org.

Since yesterday, Firefox is crashing constantly. Any action taken on a page can cause it to crash. My cache and cookies have been cleared (every time I end a session), my computer has been restarted (now 20x). I have checked settings on MFF and all looks correct. I have used for years and never had this issue but have been using another browser since yesterday afternoon because this is disruptive to work. Anybody else having issues since the update 5/29/24?

At some point after a Firefox and/or Windows update, Firefox started to stall after working for a while. When I open Firefox, I start surfing using multiple tabs, using bookmarks, typing URLs, or clicking on web links and then suddenly, the little dot in the current tab where I am trying to access another link, starts moving right and left indefinitely, apparently waiting or unable to access the desired page. After that I type well-known URLs (such as google.com) that I know "always" work, and the same thing happens. From then on Firefox cannot access any URL I throw at it (no error messages or warning of any kind) until I close Firefox and reopen. Once I reopen, the cycle repeats: it works for a while until it doesn't. I have cleared all cookies and caches, I have erased or disabled all extensions, but the problems persists. Any advise? Thank you.

Hello! I've been noticing for several versions of Firefox that the response times reported in the “Network” tab of the developer console are wrong. In Chrome it shows the true value, which are a few ms, while in Firefox they show that it takes several seconds!!!! I attach the images of the problem.

Is it a bug, or a configuration problem itself? Thanks in advance

Site (https://www.pinerolo.news/

The animated images of the articles are loaded once every 3. On Chrome Android I have no problem.

I solve it manually by resizing the page, so they load.

Where could the problem be? In the animation of their site? Do you have any advice on a fix?

Since the latest update, when I right-click on a bookmark or an item in the history list (from the menu or the bookmarks toolbar), I still get the menu that has items like "Open in new tab" or "Edit Bookmark".

However, the focus for the mouse stays on the previous menu, so that I can't click on anything in the "right-click menu", instead it is interpreted as a click in some random item in the previous menu.

Going into troubleshoot mode didn't help, so I don't think it's my configuration causing this.

Firefox spawn too many child processess, with cause the browser to freeze.

Proposed solution:

Reduce to absolute minimum the spawn child processess. The value should be set according to the device performance and additionally show allow the user to set manually the limits.

Example: 1 (maximal 3) child process per tab/window

Please help me to understand why I keep getting the 'Gah! Your tab just crashed' message. This only started a couple of weeks ago, but is extremely annoying and makes me doubt the integrity of Firefox. The problem can be circumvented (at least for a while) by closing and re-opening Firefox, but I'd prefer not to have to keep doing this.

Hi,

So I got a new ultra-ultra wide 32:9 monitor and I noticed when I have firefox maximized on my new monitor and switch focus to a different window all of the text on tabs on the full screened firefox would go very blurry. If I had the same firefox windows full sized on my 16:9 secondary monitor this didn't happen. I then tried having the windows not maximized on the new monitor and it did not do this behavior when it was occupying what I would say was 1/3 of the screen width but if I stretched the screen too far it would again go back to this blurry behavior. So it seems like the text for the tabs behaves differently after the firefox window is stretched to a certain width. On the non-stretched firefox windows the letters simply get darker which I find to look better than the blurring. I added a screenshot that shows the differences I am seeing, the firefox window on the bottom screen shows the blurring, if you look at what would be the left middle side of the screenshot, while the top and bottom middle firefox windows show what it seems like it should look like.

Thanks, Dan

I have been using Firefox as my preferred browser on Windows 10 Home and Pro systems for a considerable time and have recommended it to many Windows and Android users.

Windows 10 Home ver 10.0.19045 has recently been unable to access many well-known websites due to

Secure Connection Failed - An error occurred during a connection to <website's https url> PR_END_OF_FILE_ERROR.

There are multiple reports of this problem from 2023 up into 2024 in Mozilla support and across the web, but no solutions. Curiously all of the problem reports mention Firefox not any other browser. Suggestions to try multiple fixes, but none have resolved the problem.

One posting on Mozilla Support marked RESOLVED says the problem mysteriously went away for that user. Lots of people still seem to be having this problem, so how about a fix.

Sent from Brave browser,

my firefox browser switches to how it will look on windows 7 for a split second and back to original view, i run it on windows 11 , also when i run multiple firefox windows minimized side by side it often crashes

Hello, I have a problem: After an automatic update of the language packs, parts of the Firefox menu (version 126.0) are displayed in EN. Parts in DE. Seems to be related to the update... how can I change this again? I have already changed the language settings. Didn't help...it appeared after an automatic update on May 28. Thanks for an idea :)

Im using mozilla for long time but now its nit working https://showpm.com.co/ this site is not opening in mozilla please help me

I have been facing a very strange situation/bug (likely some addon breaking my Firefox) where I am not able to navigate/load certain sites and certain pages. Here are details:

What is working: 1. I can go to google, amazon, yahoo, and certain other websites home page, and type certain queries in the google.

What is not working: 1. I can't load Duckduckgo(dot)com, nor ddg(dot)gg 2. Though I can open Google(dot)com, but I can not search anything in Google. I can see autocompleted/suggested results in Google, but nothing happens when I click on those autocompleted/suggested queries (screenshot attached, see lower left corner, *.gstatic.com/*.google.com is loading forever). 3. I can't open any addons/extensions. For eg. Tab Session Manager, or even Bitwarden does not load when I click on it, except it shows a pixel on the right corner of addon button on Firefox Toolbar (screenshot attached for that pixel towards the right lower corner of the icon).

What I have tried already - 1. Firefox is up to date as of a few minutes ago. 2. Underlying OS is up-to-date as of a few minutes ago. 3. I have tried disabling all addons and it did fix the problem. 4. I tried changing theme (which was default black) to default, and it did not fix the problem. 5. Tried restarting PC and it did not solve the problem. 6. I tried troubleshooting mode and it DID fix the problem while I was in troubleshooting mode, at least sites were loading. But as I exited troubleshooting mode, addons started loading for a few seconds, and then once Firefox is loaded fully, I started experiencing the same problem. 7. Tried toggle HTTP3 enable/disable, which did not fix the problem. 8. Followed Firefox troubleshooting guides, it did not solve the problem (except troubleshooting mode). I tried disabling hardware acceleration and disabled any protection modes, DNS over HTTPs and other settings which might interfere in site loading - none of that worked.

My hypothesis so far - As I can access some sites on the internet, I have ruled out DNS issues and networking issues. I tried disabling all addons and it did not fix the issue (except when in troubleshooting mode) - which tells me addons are not necessarily a problem. However, I could not find what all things troubleshooting mode disables, and perhaps I should find that out. Could anyone please share any insights or your thoughts on what I might be missing? Firefox is my primary browser and a lot of my tasks are pending from over a day now. Any help is greatly appreciated! Thanks a lot!
