Firefox Community Forum

I use Firefox under Fedora (I'm two OS versions behind, must upgrade soon). I open very many tabs each day then work through them, theoretically every day, in practice they accumulate and I deal with them when I can. I rely on the tabs loading correctly on restart, but today they didn't, instead the set of tabs that were opened a few days ago loaded, and I lost everything I had done since then. Is there a way to retrieve the tabs that were opened just before this happened, ie around 15-20 hours ago? Ideally, again, I would merge them with the current ones, but reopening the old ones would take much much longer than reopening the new ones. Thank you for any advice.

latest update seems to have broken firefox 155.0.1. It opens but then becomes unresponsive. Two different PC, both win 10. How can I revert to previous?

I can not get extra info from troubleshooting page cause FF won't open so as to be used.

I used to be able to use UK in the free VPN list, over the last 3 days, since I updated my firefox, I am unable to do so. Has anyone else down under had this problem, if so is there a solution to the issue.

Thanks in advance

I am on version 155 of the browser, and the sidebar is not showing up for me. Clicking the sidebar toggle button also does nothing. I've tried going into settings and toggling the show sidebar option, but that also doesn't do anything, as if the sidebar feature doesn't exist. Toggling vertical tabs just makes the tab bar disappear, and I've tried both the options menu and right-clicking the side bar toggle button. Is there an error, or am I missing something?

Hi ì just want to ask how does it happen that when I use the Firefox bar search engine and when I type something to search i find myself typing in google search bar even when i haven chosen Firefox as a or on defaulter.

And also Please check for me what is making my data to finish so quickly, it was not like that at first but now my data doesn't last for long anymore.

Thank you M

Hi, so since around update 153.0 i've had this persistient issue of whenever I am forced to re-open firefox (whether by an update, a restart on my computer or a crash) it begins to persistiently quit responding and will never work until i close it. After a LONG while of just trying to open it again, it begins to run, but it also signs me out of a good handful of things, so I end up spending 20+ minutes signing in on everything (considering 2fa on some of those things). This used to just happen with the big number updates, but tonight my computer had to restart and I experienced the same thing happening with firefox just loading and loading. I tried letting it sit and of course it did nothing, I attempted to use troubleshoot mode and there was virtually no difference (it was still frozen until i closed it). The only things I haven't done are the nuclear options of refreshing or reinstalling firefox (mainly because I have a lot of extension settings I would rather not lose because I don't remember all of it). I am writing this on a mobile tablet right now because my computer is still experiencing this persistiently, no matter what i do now, and it's becoming annoying because of the fact that i do have to sign into everything EVERY TIME now it seems. Extra information about my settings to answer some of the "do you have (this setting) on?" or other functional questions: -I keep cookies on and stored on the device -I have hardware accelleration off -I had several extensions on including ublock origin, but again, troubleshoot mode (which disables all extensions temporarily) had the exact same result of firefox hanging. Disabling certain extensions manually also didn't work. -i can't provide exact technical info on my pc since im not on it rn nor really want to deal with fighting it any longer tonight to write this but my computer is on the lower-end, but can still run and does run things like discord/steam fine; firefox started persistiently freezing after a fresh restart of my computer, and I didn't open anything outside of firefox and related firefox modes (ie private browsing) attempting to troubleshoot today. -last time i signed back in before it kept crashing constantly was 4 days ago I really hope this explains my issue well enough and I hope someone can give some advice on my next step forward. I'm becoming a little desparate for answers since i don't know how long this goose chase of constantly re-logging into everything the services i'm logging back into will tolerate, as one of my emails is now blocking my main 2fa method for some reason, so I'm a little worried.

Greetings!

I have a few questions if you'd be willing to answer.

There have been some changes and new additions to the croatian dictionary (https://github.com/krunose/hunspell-hr) and as such, the Firefox dictionary could be updated.

Can you confirm that the dictionaries and language packs are separate additions and that the dictionaries are used for spellchecking? https://addons.mozilla.org/en-US/firefox/language-tools/

When is the spellcheck dictionary installed, only when the user installs it or when the user installs a language pack?

In addition, the croatian dictionary has not been active for the past eight years. Maintainer of the current hunspell-hr dictionary has said that person behind the croatian dictionary extension has not responded for several years. https://addons.mozilla.org/en-US/firefox/addon/croatian-dictionary/ https://github.com/akoncic/mozillacroatiandictionary

What are your suggestions how to handel the situation? There is already a fork of the extension that is used as a pull request but has not been merged for years. https://github.com/krunose/mozillacroatiandictionary

Thank you for your understanding.

Have a wonderful rest of the day.

Доброго времени суток.

Я установил сертификаты по инструкции, которая лежит на s.sber.ru/70VQ2B . После этого не прогружается полностью окно входа на online.sberbank.ru (не видно содержимого фреймов). Проблема полностью аналогична описанной здесь: https://support.mozilla.org/ru/questions/1597415

Firefox ESR115.40 (64-разрядный, Windows 7) - страница выглядит, как на скриншоте по ссылке выше.

Установлены скачанные сертификаты в самом браузере, они отображаются в разделе Управление сертификатами -> Центры сертификации. После этого абсолютно ничего не изменилось.

Может, надо еще что-то сделать? Или на Firefox ESR115.40 вообще работать не будет? До перехода на сертификат от Минцифры России проблем не было.

About two months ago, after various Windows and Firefox updates, I can no longer make Firefox the default browser. In Windows Default Apps the only option for FF is to make it the default program for Adobe Acrobat Document. Choosing Make FF Default through the browser does not work either. Additionally, I’ tried numerous suggestions, using AI help offered by both FF and Chrome, without success.

The OS is not allowing me to make Firefox the default browser. Is there any way around this?

Any suggestions?

I am looking for an addon which displays times in different locations. I find one, FoxClock, which initially seems to meet my need. However, although the developer says its safe, and it has a Recommended badge, text in the app description says "Access your data for all websites." This may be 'honest' but it seems to be honest at the level of a thief saying "I'm going to rob you." WHY would a clock app need access to my data for all websites? Why would a clock app displaying on my desktop, not my browser, need to access any info about my data for any website? Poor coding? Lazy coding? Dangerous coding? Is this only a result of less than nuanced messaging by the developer or Mozilla, by using a generic message, rather than one which accurately states the 'access' is only for specified installation needs? Or another understandable safe reason? I'd like an explanation, since it does call into question the degree of security offered by Mozilla.

I have logged into TinyURL.com MANY times using Firefox. Now, I get a Cloudflare Validation Error when trying to do so (see attached screenshot/snip).

This was done in Troubleshooting mode, but is the same in standard mode, though I have no extensions enabled. I've tried turning Protection Tracking off; no luck. - We use ZoneAlarm, but the Web Secure functions are all disabled. - I have the same issue on 2 PC's, one Windows 10 and the other Windows 11, 64-bit. - I'm on FF release 150.0.2 - 64-bit, and both Windows installs are fully updated and kept that way. - I've reached out to TinyURL in hopes of resolving the issue. They suggested many of the above steps but not resolved this issue. - HOWEVER, I've found that login via Google Chrome IS seamless - no issues.

What is it with Firefox that it's having issues with the Cloudflare "Human" check? I've checked the Cloudflare site; all conditions are good, and this very setup passed the "Turnstile" check.

FF is my #1 preferred browser, so please look into this. I see that others have posted similar issues over multiple years here (but a search of support articles didn't find one . . .)

Thanks,
