I occasionally visited this site https://referti-empoli.uslcentro.toscana.it/portalepaziente_user/user-login (it's a site managed by the local health authorities). I am reported that a safe connection cannot be established with the message PR_END_OF_FILE_ERROR. I am not shown any option to consider this site SAFE (no matter what, it's SAFE and I need to access it occasionally). I also use ESET anti-virus software. I can access through other browser, at least the show me it couldn't be safe but allow me to go on. I don't want to switch browser once in a while to navigate. I want to use Firefox in any case (or switch to another one that allows me to). How can I make it work (apart from deleting cache, temp files and history, which did not work)? Thank you.

Does anyone have experience with this phenomenon:

When you click on a torrent link on a page opened in Firefox 83 (and above), the first window pops up, but the second one (in which uTorrent would come) is no longer. Nothing happens. Specifically, the entry is C: \ ProgramData \ Microsoft \ Windows \ WER \ ReportArchive \ AppCrash_uTorrent.exe....

If I revert to Firefox 82 or 78.6esr, the error will not occur.

If I choose not to download uTorrent but to download the torrent file, it works fine with all versions of Firefox.

in about:config page the options: browser.tabs.warnOnClose (true - default) browser.tabs.warnOnCloseOtherTabs (true - default) browser.sessionstore.warnOnQuit (false - default) browser.warnOnQuit true (true - default)

But when i do Ctrl+q accidentally, it closes the only Firefox window i have. This window has many tabs open. Yes it restore next time, but i want FF to ask me before closing it.

In order to use my preferred browser, MetaGer, I have to change the default search engine every time I open Firefox. After setting the default search engine, Firefox reverts to Google after relaunch. How do I fix this? I'm using Firefox 85 with OS 10.13.6 High Sierra. Thanks

Hi, other than the default search engines, I tried adding some more to Firefox in the options. The method I did this was, say I need to add Yandex search engine, I went to yandex.com https://yandex.com and clicked the three dots and the address bar and selected "add search engine" but when i go to options>search, the engines i added are in the drop down list (1), but not in the grid table (2)where you can add a keyword or remove the engine.

Is there a way to fix this?

I've been struggling today with accessing two systems on my work laptop. As I'm an administrator on both sites, I've been purposely using "private mode" browser sessions in Firefox (my default and fav) but I was surprised to see that the private mode appears to be "save" some of the session data from those systems - at least temporarily until I close all of those windows entirely?

I log in to one of those corporate sites with a username + password, then attempt to login to the other one in a separate tab, but it immediately attempts to auto-login me in with the credentials from the first site (which doesn't work as both sites require a different username/password for security reasons). I tried several combinations: I used separate private browser windows (instead of tabs) and the same thing happens. It's like it shares data across the instances? I also tried the reverse - logging into the 2nd system first on a fresh instance, then login to the first, and the same thing happens with a similar "invalid login" error.

Maybe its something weird about the auth on our network, like SSO? ...

I have noticed similar though where I've had other, multiple private browser sessions open on my personal laptop and even though I've closed one of them, activity from the site I closed has continued to happen in the background because the other private windows remained open ...

hi! sometimes when trying to visit a site by clicking a google search result link, firefox stops it and shows:

Warning: Potential Security Risk Ahead Firefox detected a potential security threat and did not continue to (website).com. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details...

So my question is, would attackers be able to steal such information if i never enter any? ie, if i only visit the site to read about things...

thanks for your reply!

There used to be separate "reload" and "stop" buttons available that I can pick via "Customize" menu and put next to the address bar. The archived solution suggested here (https://support.mozilla.org/en-US/questions/1203285) doesn't or does no longer work. Now what? I have the lastest version of firefox (85).

The ESR release is apparently behind an update, likely security oriented (the site ESR is rejected by is a Bank). I've been told by the site that they test (essentially) Chrome...and go with THEIR updates, if it suits their purposes. They suggested blowing away the ESR history (...cookies and all of it) and restarting ESR. Afteer that didn't work, I'm presuming the fix the Bank wants is in FF 85.0.2 and not in 78.7.1 ESR. But, I'm guessing.

I realize ESR stages ESR releases to follow FF so to allow testing ahead of FF auto update migrations. It's one reason why I use ESR most of the time. But, I think it would help if we could have some way to associate ESR's release cycles (Versions) to FF (Versions) with dates and expected. Maybe it is somewhere.

Q. What is the relationship, if any, between the versions FF vs ESR? Is ESR 78.7.1 = FF 78.7.1 or what? Q. If not, what? Where/What is the relationship and is the timing set or variable on progressions of ESR?

Thx wgk

For some reason I was just upgraded to a new version of Firefox. I have lost everything I had on the old version. Completely lost all book marks etc. Is there any way to access them again, or delete this new version? Very frustrated! Larry

Whenever I zoom into images in Firefox (example), the image smoothing makes them look blurry, especially on low resolution images. Is there any way to disable image smoothing of Firefox?

sometimes when i go to certain sites i use often, it says i need to update my browser to use certain features, but i already did update my browser to the latest update, apparently many websites keep saying im still in firefox 78 when i try to update it says its already updated to the latest version, is there any way to fix this without reinstalling firefox.

Hi. I'm trying to organise my bookmarks, and whilst I am able to add, move and remove bookmarks themselves, I can't do anything about folders, even duplicates. Deleting in Firefox's GUI does nothing, and if I try to use a bookmark managing extension, it doesn't work either. What's going on?

I've been digging around in my system for a corresponding .txt file or whatever to manually edit, but it seems it's all on Mozilla's servers, or the file is in some obscure format I can't easily edit. Is this something to do with Firefox Sync?

Hello! After various problems with my MacBook I had to delete everything from my hard drive. After installing BigSur 11.2.3 and restoring things from my TimeMachine backup all my Firefox bookmarks got lost. I understood how I can restore them but I don't know what file to look for in the TimeMachine backup that should contain my bookmarks... I would also like to restore my passwords if possible. Anyone can help?

Hi, I work for a large corporation. My employer enforces an annoying policy that when loading Firefox it defaults to the corporate intranet. This is really slow and hampers my productivity big time as I very often (re)load Firefox. Especially when in video sharing calls with customers this is extremely annoying as I'm working 99.9 % from home on a lousy VPN bandwidth.

Can I enforce somehow that Firefox loads a blank page by default, essentially overriding the group policy ? e.g. by using the command line when clicking on the Firefox icon in Windows 10 ?

      or via a batch file or some other way which can improve this situation ?

The installed version of FF is 78.8.0esr (64-bits), should be latest.

Your support is most welcome ! Cordially Yours, Jean.
