Every damn time Firefox decides to update, it deletes every single one of my Stylus themes. And yet long standing issues like the Bookmark Tool Bar going blank if you watch video in full screen for too long still exist (10+ years now).

Also, whenever Firefox updates, it royally screws up the session that was active. Instead of opening every window and tab that was open, most of the time only one window gets restored. Sometimes none of the windows get restored because Firefox stupidly opens and then closes again, and then when it opens again, all you get is a page telling you about the stupid feature you don't care about that Firefox updated and ruined everything for.

I've used Slack every day for the past decade, and Firefox has been my primary browser for some time now. I've never had an issue with the two, but now, Firefox is reliably crashing every time I attempt to open Slack.

I've tried clearing my cache both broadly and specific to Slack, with neither producing results. Even tried deleting all cookies on Firefox, which was a bit of a pain, and it was no help.

I did read up on some people encountering a similar issue that could be fixed by deleting the Slack entry in "about:serviceworkers," but this did not help here.

The only extension I'm running is uBlock Origin, which I've been running for probably as long as I've been using Firefox, and that has never presented an issue before either.

Would appreciate any help or advice on the matter.

It would be extremely useful to have a single hotkey to open all currently playing videos or audio in Picture-in-Picture (PiP) mode in Firefox.

Currently, opening each video manually is time-consuming if multiple media are playing across tabs. A dedicated hotkey would:

Save time for users managing multiple media.

Improve multitasking and media consumption workflow.

Enhance accessibility for keyboard shortcut users.

Suggested Hotkey: Ctrl + Alt + P (P = PiP, easy to remember, low conflict with other shortcuts)

Optional: Support toggling all PiP windows on/off with the same shortcut could further streamline the experience.

Recently I uninstalled then reinstalled Firefox on my Samsung A71 because I couldn't remove a timer I set on the app. I continued using Firefox on Android as usual for about three or four days but tonight I discovered that my Android history isn't syncing up to Windows 10 Firefox on my HP Pavilion. I signed out on Android, then signed back in again but my Android history still didn't appear on Windows. I tried several more times, using both the QR code and my email. I then uninstalled FF on Android and reinstalled and signed back in again but only a few items appeared in my Windows history. Android won't show me my current tabs on Windows as I type this either and the sync now button is doing nothing. Is there anything I can do fix this?

(P.S. both versions are up to date)

On July 12th, Firefox updated and I was logged out of one of my gmail accounts. I have a file called "Old Firefox data" and I was wondering if I'd be able to get back in. Before you ask, I tried going through google and it didn't let me in. Unless there's a way to run the old version temporarily, I'm not sure how to fix this.

Thank you for your help.

I know this is probably not possible, but thought I'd ask.

My example would be my pinned email tab. Is there some way to create immediate access with a shortcut, rather that a bookmark, or having to navigate to the beginning of the tab session?

I deleted all the shortcuts from Firefox desktop browser's homepage and now I cannot add them back.

There are no blank shortcut icons on the page anymore. No setting to enable them. Shortcuts are enabled. Page is mostly blank, only has Firefox icon.

I tried to close and open Firefox as well as disabling and enabling the shortcut setting. Adding more rows did not do anything.

Before this issue occurred, I had one shortcut on the page that was linking to localhost. I opened the edit window to the shortcut and pasted the same address and saved changes. After that I removed the shortcut. All of the blank tiles immediately got removed from page and I had no way of adding more shortcuts.

I get this from Microsoft 365 excel when opening an .xlsx file: "Unsupported Browser Office uses new browser technology and works best in the latest browsers. Please upgrade your browser"

Why?

Since a few weeks I have been encountering an issue where tabs in Firefox would frequently crash. I do have various add-ons installed, however I haven't installed any new ones around the time the issue has been occurring. I've been unable to track down which add-on or if any add-on might be causing this.

Trying to search for this issue all I could come up with is that it might be an issue of a faulty CPU. I have an i9-13900KF which has been known to be part of the Intel generation with serious flaws. However I already installed a BIOS update and applied Intel's recommended settings to undervolt the CPU to prevent any issues. This was well before the Firefox tab crashing issue happened. So I'm not sure if it can really be the issue of a faulty CPU, but I've also had issues of other programs randomly crashing recently (like Discord or Steam).

The tab crash can occur on any website, for example Youtube, Duckduckgo, Protonmail, etc. The crash reason always is either "EXCEPTION_ACCESS_VIOLATION_READ" or just "EXCEPTION_ACCESS_VIOLATION". The crash also most of the time (but not always) occurs when loading the page itself or a video / live stream on it. But not when browsing an already loaded page (for example this forum post page I'm writing right now).

Here are some of the crash reports I've submitted:

EXCEPTION_ACCESS_VIOLATION_READ: https://crash-stats.mozilla.org/report/index/60309ae8-8cad-43ac-8b9b-172b10250815 https://crash-stats.mozilla.org/report/index/fecef0ab-d874-4cb5-990b-e49650250815

Rather rare "EXCEPTION_ACCESS_VIOLATION": https://crash-stats.mozilla.org/report/index/114b26fa-4e10-442c-bbd5-406630250812

Could someone help me narrow down this issue? Can it really be a faulty CPU and I need to trade mine in?

Sometimes when I sign in on Microsoft Outlook's email portal - a multistep process requiring authentication on one's phone - it says: "Hang on a minute while we sign you out" and then boots me, forcing me to sign in again. For awhile this was happening only occasionally, and the workaround was to delete all cookies for Microsoft online and Office. But now this is happening more frequently, and sometimes it happens immediately after deleting the cookies. In effect, Outlook on Firefox creates cookies that then prevent it from working. And it doesn't matter whether you say yes or no to "Stay signed in?" at the end of the sign-in process.

I reached out to Microsoft tech support, and they basically said this is a Firefox issue because it doesn't happen on Chrome or Edge.

Anyone else encounter this?

I have the shoutcast page with my station name on it which is w50scountry but when i click to listen it is playing your music instead of my music. How can I get it to recognize my stream and play it so i can be herd on line ? Arthur

I am trying to log into Jetstar to make a booking and the site just closed down and keeps telling me to 'try again'. No luck. I've closed the computer - reopened - delayed the 'try again' request and cannot access Jetstar. I need urgently

to make a booking.

Thanks you helenmary

Hi there,

I'm wondering if there is any support team or moderators who are in charge of the Recommended stories on the Firefox New Tab now that Pocket support has ended?

Is there any guidance or point of contact for websites featuring (or wanting to feature) in the Recommended section - like with Google Discover or Apple News?

Thanks so much!

I just accepted a FireFox update and now it will not load any new pages. In your previous update it no longer loads the popular page previews either. I am on windows 10 for now and will be installing Windows 11 in the next two days.

I have been a great supporter of FireFox and Mozilla and must say you guys are dropping the ball. Less and less clients are building stuff to work with your browser. Its making it difficult.

One recent example is Google Meets ( I hate it, but others use it) It wont run on your browser. Job applications often fail on your browser too.

The Bitwarden extension no longer works

If there is anything you can do today to get your browser to work again, Ill continue using it. But unfortunately I can no longer spend time troubleshooting it.

Здавствуйте. Играю в браузерную игру в Мозила фаерфокс и все еще наблюдаю проблему самовольной перезагрузки вкладок. Я уже писал и описывал эту проблему но вы так ничего и не исправили. И вот сейчас я обновил Фаерфокс и снова эта проблема. Поблема вот в чем: Я играю в игру в полноэкранном режиме где идут или выполняются активные игровые действия, так же я делаю активные действия мышью. И вдруг браузер САМ выводит меня из полноэкранного режима, начинает обновлять вкладку с игрой. Из за этого весь игровой процесс прерывается и мне снова загружает игру! Честно сказать это уже надоело. Не возможно играть нормально, в любую минуту браузер начинает сам обновлять вкладки. Пишу вам второй раз, исправьте это. Скриншот с игрой я вам приложу, а так же опишу название и айди игры на платформе соцсети Вконтакте. Игра "Клондайк - Пропавшая экспедиция" Номер игры App3083242. Или ссылка на игру https://vk.com/app3083242

Надеюсь вы исправите наконец эту проблему!

apply patch failed message. version 143.0.1 September 19 2025 update. Yet states "updated" Details saying message apply patch failed is found via firefox browser settings-firefox update history-details. I noticed that on that exact day of the update Audible books will not play as they did previously on the same day prior to update. They play on every other browser but firefox.
