Firefox Community Forum

This is the second day my Firefox browser has periodically dropped connectivity on my Mac. When I switch to Chrome, it connects fine, so it's clearly the browser, not my WiFi. I updated my Mac to the latest software. I tried changing proxy settings and deleting cookies, but nothing has helped.

I transferred my FireFox files from my older model macbook pro to this macbook air (M3) and maintained/used the FF3/oes daily. I installed the latest update, Tahoe 26.7, before shutting down my computer last night and this morning I discovered that my FireFox windows and tabs had disappeared, completely. Can these files be recovered, and if so, what are the steps?

This computer works fine with Firefox, but on my other one it opens to Sorry, we're having trouble getting your pages back. I don't want them back. But Ok, I'll go along with you. Try Start New Session: just buffers. View Previous Tabs? Can't remove the checks. Just buffers. I end up either shutting it down myself through Task Manger (no other way works) or waiting for the popup that Firefox isn't working, what do I want to do? I can't close it with the X. Restarting and shutting down then turning on the computer again didn't do any good.

I had this problem a few months ago, but not as severe. Hard booting worked, and as long as I specifically exited Firefox at the end, with the drop down menu, I could use Firefox. Now I can't use it on my other computer, which is where I prefer to work. I have to use something worse.

Had to restore entire backup image of C: (boot) SSD that was saved on an external USB drive. I had been using FF 156, but the image restored FF 155. My FF profile is always stored on D: (internal HDD).

I launched FF and got a message that my profile was created with a newer version of FF and might not be compatible. The only option was to create a new profile or exit. I created a new profile but when FF opened I had no direct access to my existing profile on D: HDD. It wasn't listed when I clicked the Profiles button on the toolbar.

Came across a site that said to run Start>Run>firefox.exe - P. A box opened that listed both the newly created profile and my existing one on D: HDD. I selected the profile on D: and FF launched without any problems - everything fully restored. So if the existing profile is compatible, why was it so difficult to select it?

How 'bout this..? When FF detects that an existing profile was made with a newer FF version than currently running, why not give the user the option to install the latest FF update on that same message screen, in addition to the option to create a new profile? Then just relaunching FF after the update should allow an existing profile to be selected/used. Obviously existing profiles are compatible with FF updates since everything still works after routine updating.

Exact same thing happened with Thunderbird after reimaging C: because an older version was restored. I tried running thunderbird,exe -P without knowing if that would even work, and it easily allowed me to restore all 5 of my mailbox profiles with thousands of emails that are stored on D: in seconds.

Please make things easier...!

I am using Ubuntu Linux on a desktop PC running Firefox in kiosk mode going to a specific web page - Every time Firefox does an update (since version 147) the kiosk mode stops working. The very latest update, after a reboot, just shows the menu bars and not Firefox going to that specified web page. Has the kiosk code changed since v147 ?

Have used this wi-fi before on Fedora Workstation 44. Reinstalled linux using Xfce Fedora 44. Selected now from list of available wi-fi connections and indicates connected at 79%. Firefox not able to use connection? Thanks for any help available.

With each update by Mozilla for Firefox for Windows, I lose abilities on sites I previously had. For instance, before the last two updates, I had no problem to add or paste an image into chatgpt. Now it Firefox will not allow me. If I change to any other browser (Duckduckgo, chrome, etc.) then I can add and paste images. This is not the only website I have had problems with since the last updates, and in every instance changing to another browser fixes the problem. I have made no changes to my settings with any update.

20/09/2026 CROSSWORD SPOILERS

The crossword on the home page today has a clue has a very misleading answer. It gives the clue "a quartet, but doubled", which should be Octet, however it uses the very outdated and (personally believed to be) inappropriate answer as it would make sense that quarTET would then imply ocTET. A more apt clue should have been, "Triad, but for eight". Very aware this is a personal gripe rather than an actual issue, but is there a process where the crosswords are checked or are they pulled from a 3rd party site?

I recently downloaded Firefox and was trying to import all of my Chrome data, including my bookmarks. For some reason when I go to import my browser data, there isn't even a option to import bookmarks. One of my other chrome accounts has the option to import bookmarks (a old work account I no longer use anymore), but my personal account just doesn't have it. Am I missing a step in this process or is there something I need to do on chrome to make my bookmarks accessible to Firefox? I really don't want to go in a manually add all my bookmarks..

Why is Firefox losing my bookmarks? They're being replaced with a little globe, and they don't work. Also, yesterday's history was lacking at least two-thirds of the sites I visited.

The current version of Firefox is very frustrating to use. It often will not let me enter a password but will send me to the saved passwords. I do not want to put all my passwords on the computer. I have 2 U tube accounts, and the new Firefox will not let me enter the account info directly, but sends me to Google. I have had to resort to using Microsoft Edge out of sheer frustration with Firefox. Previous versions of Firefox did not have these problems

In the past couple of weeks (say Sept 2026), Firefox has started signing me out of everything when it closes or updates even though 'clear browsing data' is UNchecked. What else can I do to stop this?
