Hi everyone.

Basically when the browser is (I think) idle while watching YouTube, FF is constantly backing up (the timestamp in the backup file name keeps getting updated). From the settings page I thought it once every 24 hours. I noticed from higher than normal CPU usage impacting FF and the Windows search indexer. Which reverted to normal once I disabled the backup.

I checked the about config:

• browser.backup.scheduled.minimum-time-between-backups-seconds

Is set to 24 hours (86400 seconds)

But I also noticed:

• browser.backup.scheduled.idle-threshold-seconds

Is set to 15 seconds(!). Is that what I think it is? Back up whenever there's a 15 sec idle window, regardless of the minimum? Can I safely make that 86400 seconds too, or does it do something else entirely?

Many thanks in advance.

Hello everyone.

I've been having some issues with Mozilla lately. I don't know if my CPU is in bad condition or not but, when I change tabs through my Windows, say changing tabs from Mozilla to Spotify and changing it back to Mozilla, my CPU gets very full, causing my cursor to lag, and Mozilla to be unresponsive for a couple of seconds first and it gets kinda worse as I continue to use my PC, causing the lag to occur for over 10 seconds.

I have seen some similar complaints on the web but they date back to 2014ish times.

What do you think? Is it somewhat my CPU's problem or did Mozilla's handling get worse over a patch or something?

I enjoy Mozilla and don't want to quit using it. Any help would be much appreciated.

I met the same problem as https://support.mozilla.org/en-US/que.../1191123

I have read this https://support.mozilla.org/en-US/kb/forum-response-firefox-sync-verifica...

I have tried waiting for more than 24h, not working, and submitted a request at Bugzilla (maybe it's because I didn't write the request in the right way so I haven't got response yet).

I have some so many bookmarks in my firefox account and passwords in my lockwise account. Please help me out, my account email is xxxxxxxxxx@xx.xxx

When I logged in this morning my FireFox screen had changed. The window for searches had disappeared and the "pocket" selections were all about India and its events. None of the previous options were there. What happened and how do I get back to where things were?

I really appreciate Firefox's built in translator; it is extremely helpful. However there is one thing that bugs me, when translating a page that has multiple language options. For example, when translating a page from German to English, the word "Deutsch" (often listed in the website's built in language settings) is translated not to "German", but to "English". While technically correct in that the page is now displaying English thanks to the Firefox translation, it would probably be better to show "German" so that it is easier to switch the website language and not have a duplicate "English" option in the website's dropdown menu. I have noticed this on multiple websites, specifically with German, but it might be with other languages as well. Hopefully this explanation of the issue makes sense, and see my attached screenshot which shows this issue. Please let me know if there is somewhere else I should submit this too.

I was really shocked and horrified to see Firefox place the Qatari regime's propaganda mouthpiece on my home screen. The Qatari regime is one of the worlds worst abusers of human rights. It allows no political parties, tolerates no criticism, and severely punishes online dissent. It has absolutely no LGBQ rights, is deeply misogynistic and antisemitic and uses slave labor extensively. Additionally, it is a known supporter of extremism and terrorism. It is not OK to push their propaganda outlet on the front page.

I am the developer of FastF1, an open source Python package for downloading and analyzing Formula 1 race results, timing data and telemetry. The package is widely used in the fan community for independent analysis of results. For some advanced features, the addon requires users to authenticate with their Formula1/F1TV account. Since their services don't have an open login API, a companion addon is required to allow users to sign in using their browser and the official website.

I have just noticed that my developer account has been banned and the addon was blocked in Firefox. I have not received any email about this and don't know why exactly this decision was made. I'd like appeal this and reinstate my account and the addon, but I don't know how to proceed from here.

FastF1 and the companion addon are fully open source and intend no harm to users. https://github.com/theOehrly/Fast-F1 https://github.com/theOehrly/fastf1-companion

I hope this problem can be resolved.

I downloaded Firefox today and saw there was a VPN option but it is not working. It asks me to sign in and per the instructions the clickable icon at the top should now have an option to enable but it just asks me to sign in again. I am from Canada and it says my region is available for this program.

As of last week, FF works for a few minutes on startup, but then when you open a new tab and try to go to a site you just get the dancing period, nothing opens. Already open tabs with sites generally still work, but sometimes crash the tabs after a bit. We've tried starting without extensions, uninstalling and reinstalling FF, changing the profile, logging in the PC (Win 10, up to date) with a different login, running SFC and DISM on the PC, and just about everything else.

Opening the FF console shows this message when the tab just rocks the period:

WindowsJumpLists: Failed to fetch favicon for https://online.adp.com/signin/v1/?APPID=WFNPortal&productId=80e309c3-7085-bae1-e053-3505430b5495&returnURL=https://workforcenow.adp.com/&callingAppId=WFN&TARGET=-SM-https://workforcenow.adp.com/theme/admin.html NS_ERROR_FAILURE: WindowsJumpLists.sys.mjs:257:29

Edge works perfectly (and unfortunately, I'm having to use Edge to enter this ticket.). Other applications don't have any issues. I'm not having this issue on 2 other similar PCs I have that run FF, only this one.

Any ideas of what might be the issue with FF on this PC? Thanks, Alex

I am trying to move one tab from one window to another. It says I should be able to move it just by clicking on the tab and dragging it to the window I want to move it to. But, when I try this nothing happens, it won't move.

Want can I do to resolve this?

Thanks

First of all I've noticed that even logging in to the account management page doesn't work with my vpn on. So of course sync itself doesn't either. It works perfectly fine with it off though. Is there an IP address that I can add to split tunneling to allow only the sync/FF account manager through my vpn? Or another way I'm not aware of? I'd rather not have to allow the whole browser through my vpn if possible.

Either removing certain ones I don't care about or getting ones back I may have already taken out?

I don't see either of those functions any more but I swear there was a way to do it just a month ago.

Сегодня 23.04.2026, я открываю браузер и вижу, что моя строка и ярлыки находятся сверху, а не в центре(1 скриншот). Вчера 22.04.2026 все было хорошо, я покажу на 2 скрине как это должно выглядеть. Хочу заметить что у меня включена функция Handoff и она мне удобна, но мне неприятно видеть блок с ярлыками и строкой не по центру. Я использую тему ffultima, скажу еще раз, вчера все было нормально.

i am experiencing an issue with firefox where backup (Firefox Backup) is not working since version 148.0

problem: - when I try to create a backup, i get the error: “Hmm, there was a problem with the backup. Please try again in a few minutes.”

what I have already tried: - enabled and disabled backup password - changed the backup folder/location - cleared browser cache - tested across multiple updates (issue persists)

- backup is enabled, but I cannot create one - the error occurs every time - restarting the browser and system did not help

Good day everybody, I am new to Firefox. I have MacBookAir 11. I added the Ecosia extension since it's my main search engine. I noticed there aren't ads popping up for Ecosia. That is how Ecosia makes money for it's sustainability projects, so, as nice as it is to not see ads, I would like them to show up for my Ecosia searches. I understand you can make an Enhanced Tracking Protection exception (and I did), but where can I find a place to make exceptions for whatever AdBlock software came already integrated to Firefox? I am liking Firefox so far. Thank you everybody. Miran.

Hello All,

I'm using Firefox (149.0.2 snap) with LUbuntu 24.04.4 LTS. Because of a wrong graphic driver, I had to turn off hardware acceleration in FF.

When FF is started the Initial "Firefox - Choose User Profile" is unreadable (see attached : wrong_screen.jpg), but if I continue (click somewhere in the window) , all the opened tabs are readable.

Once in FF, if I want to select another profile from the application menu -> .. -> manage profiles, then the "Choose User Profile" window is fine (see attached : good_screen.jpg).

I tried to start FF with the "-P" option to specify wanted profile but it continues to start with the unreadable "Choose User Profile" window.

Could someone give me a solution, except finding the good hardware driver for my computer?

Thanks Bouilla.
