При заходе на сайте ya.ru и если на нём имеется строка с видео или поиск с алисой, то начинаются сильные фризы. Это ошибка именно в firefox 142, проверенно.

After the update on the 14th, dark mode has gained weird stylistic choices that I cannot find a way to alter: namely, when closing a new tab, a white box with black font appears -as opposed to the previous darker toned grey/purple with white font. However as of writing this post, I notice that dark mode is not working on this webpage. Seeing as I have an extension enabled in addition to the basic dark mode selection in Firefox settings, I can only imagine that something was broken in the update. Please advise, the change is jarring.

Hi everyone, I’m managing an online bill information website, and some users reported an issue when they try to download or print a PDF bill using Firefox. Sometimes the print preview doesn’t load, or the layout breaks, while it works normally on other browsers.

Is there any recommended Firefox setting, extension, or workaround to prevent this issue? Also, is there a specific print CSS or PDF format Firefox prefers to handle better?

If testing is required, this is an example page where users reported the problem: https://fescoebillcheck.pk/

Thanks in advance for any guidance.

I'm running Firefox 144.0.2 (64-bit) on a Mac using Sequoia 15.4.1 OS.

At the most recent Firefox update, I added VPN.

Since then, I've had a problem with Firefox hanging. Not immediately but after varying amounts of time, 20-60 minutes. I get an "Out of Application Memory" pop-up but the usage for both Firefox and other elements are well within normal range, not high. It's completely frozen and the only way out is to do a Force Quit.

There are times when doing a shut down I notice that VPN has somehow been turned Off and once I saw a message of Background Service Error attached to it.

Having to constantly re-start Firefox is a major pain. Oh-- I did turn off the background AI thing under Tabs. I hate AI and try to turn it off everywhere I find it. A resource suck and bad for the planet.

Any help appreciated.

I recently had an issue with my computer screen. The computer itself worked fine, but the screen needed to be replaced. Stupidly, I went to the Bestbuy I bought it from to use the warranty for repair. They sent it out, I just got it back, and it says they replaced my motherboard for whatever reason. My downloads and such back up automatically, but because I didn't expect them to do something so drastic, I neglected to create a backup key for my tabs and bookmarks. Obviously, they're all gone now. Is there any way I could possibly get any of this back, or am I screwed out of luck because those morons made a drastic decision that did not need to be made? I'll apologize ahead of time for my lack of technical know-how.

Thanks

A bit over a month ago, I was away from home for several weeks. When I came back, a browser that worked perfectly before became near unusable with constant and random crashes. Sometimes they occur even with no user input. I have tried troubleshooting mode, I have removed all extensions, I have tried all the fixes I found on Google, I have reinstalled the browser, I have updated all the drivers, I have done MemTest86 which was passed with flying colours and I have even installed a firefox fork (waterfox) to try and fix this all to no avail. I have no clue where to go from here, as it feels very bizarre. All help is much appreciated.

Hello everyone, I manage a website, which focuses on mobile phone prices and SIM package information in Bangladesh. I’ve noticed that the site loads noticeably slower in Firefox than in Chrome, especially on pages with large images (like smartphone price lists). I’ve already optimized the images using WebP and enabled LiteSpeed caching on my server. Are there any Firefox-specific performance recommendations I should try (for example, about image lazy loading or compression settings)? Any advice from developers who’ve optimized for Firefox performance would be greatly appreciated. Thanks in advance.

After a few minutes of usage, firefox keeps freezing and crashing. Very frustrating. Seems to have started happening after recent OS upgrade.

Hello I am having major problems with Firefox at the moment and have done for a while. I curently have four pages open but as you can see from the attached screen shot of my Task Manager, there are 14 Firefox processes. The usage is OTT on memory and everything else. Could you tell me why this is happening? Currently it is running in Troubleshooting mode but that is not doing anything to improve the problem. It has been known to shut my computer down, as it gets too hot. I run on Windows 10 and Bitdefender is my security. All help is gratefully received. Thanks Lisa

I'm using the AI Chatbots plugin in the sidebar and I'm trying to log into Claude, but the plugin keeps asking for a verification code and Anthropic only sends a magic link email which doesn't work in this situation.

One of the recent updates changed Firefox's behaviour. It now remembers my login status to various sites when I close the browser. For example, if I was logged in to facebook when I closed the browser, I will be logged in when I open the browser and navigate to facebook.com. This was not the case until very recently (a few weeks at most). Is there a way to change this?

I have strict privacy settings, and Firefox should delete all cookies when it is closed. There are no 'exceptions'. I have 'always use private mode' checked for history. Also: I haven't changed any settings recently - something changed in Firefox.

Any advice? Thank you.

I have recently encountered reproducible failures when attempting to download files or save pages to local storage. The target directory is located on a mounted NTFS file system with the options umask=007, user=root, and group=disk. My Firefox browser is running under a non-root user account that is a member of the disk group. However, I consistently receive the error message: “XXX could not be saved because the source file could not be read.”

I would greatly appreciate anyone's assistance in resolving this issue.

Does Firefox still support automatically updating the opensearch XML description? MDN still mentions this feature: https://developer.mozilla.org/en-US/docs/Web/XML/Guides/OpenSearch#supporting_automatic_updates_for_opensearch_description

Also, in about:config, there used to be an "browser.search.update.interval" entry that specified the update interval. I can't find it anymore.

If this isn’t the right place to ask, could you point me in the right direction?

Curious about opting out of banking offers with GPC. Firefox warns users against changing advanced settings if inexperienced with making these changes. Is there a better way to opt out?
