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.

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.

the situation: we publish an internal wiki website in our intranet. the delivering server provides a certificate issued by our own microsoft active directory pki (root-intermediate-servercert). firefox is configured by gpos in order to use windows cert store, where root and intermediate are installed. but nevertheless firefox drops an error message ssl_bad_cert_domain and i do not see why. in chrome or chromium based edge everything is fine. no ssl warnings. as you can see in the attached screenshot the cert includes various san fields for different host names, which includes two ip addresses (anonymized).

any advice what do to is mostly appreciated.

Hi,

I've got 12 pinned tabs that load at Firefox start and need them to be pinned. Problem is Firefox loads only 3 tabs simultaneously, from left to right. Consequence it takes ages to load all of them and especially the last ones.

I tried to find an about:config setting to mod this behavior, unsuccessfully.

Settings I've already changed (x2): browser.tabs.remote.warmup.maxTabs 6 network.http.max-connections 2000 network.http.max-persistent-connections-per-proxy 34 network.http.max-persistent-connections-per-server 12 network.http.max-urgent-start-excessive-connections-per-host 6

Please could you point me to the correct setting ? Thanks a lot.

Does Private Browser save session data across Browser windows?

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 ...

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?

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?
