Firefox Support Forum

I have a desktop and laptop both with FF installed and synced and they ALWAYS load identical. Yesterday I set up my my new desktop in my office and I installed FF and when I logged onto my account my FF stayed the default color. This never happened before, and as I turned and looked at my old desktop I saw that it too now had the wrong theme. So I went into my kitchen were I have my laptop set up (it just upgraded itself to win 11 and I am using it as a training tool) the FF on it was no longer appearing correctly.

I have since spent 30 some hours uninstalling/reinstalling FF/ deleting my profile, remaking my profile, re-deleting my profile and making another new profile using a different email and when I install FF on ANY OTHER pc it will not load correctly, especially themes and add ons.

What the hell is causing this and how do I fix it??

On every PC I used my Revo Uninstaller Pro to uninstall FF including file remnants and then meticulously scrubbed repeatedly each PC for any leftover registry and file remnants, and then I used my file eraser program to wipe all the file slack.

If this is going to be an issue why have FF ? I spend enough time now keeping Edge disabled and dont want my fav primary browser to become a "High Maintenance" browser having to spend time EVERY TIME I TURN ON MY PC fixing this, repeatedly. Its like having to add water to your cooling system every time you start up your car before you can use it.

Any help would be enormously appreciated.

The trouble shooting information below is for the first install tonight after getting home and making the newest profile and it is seemingly staying correct, the next install on my laptop is incorrect, it has one deleted theme installed yet is "using" the default theme and the correct theme I picked is not even showing.

I got help with this from your group some weeks ago, but I had to reinstall my Ubuntu OS (linux v.20.04.4 -- using firefox) recently and can't recall the answer.

When I view a WikiSpecies list of file names (e. g., see https://species.wikimedia.org/wiki/Pentatominae), the instances which have been installed but never used should be in a different (reddish) color. I am attaching an image of a page containing a file named "Abadia" (first one on the left, just under "A") which is unused. I also am attaching an empty "Creating Abadia" which is the result of clicking on "Abadia".

Please tell me how to change the image of an unused, empty file. I recall that there were two different choices SOMEWHERE in the system, "Always" and "Never" I think: One of them forces a system-level color pattern which includes reddish unused items; the other allows the used to program arbitrary displays such as the above (typical example from the dconf editor is 'bg_color: #f0f1f2; selected_bg_color: #023C88', but this editor does not change the appearance of a file instance.

I can play videos and audios on another browser or files stored on my computer, but just now I cannot on Firefox. I saw the FAQ explanation about Windows 7, but I have been using Firefox for years including just hours ago using Windows 7. Why would this happen right now? Did some new version just get installed? If so, can I return to the prior version and turn off the automatic update?

Thanks, Phil

I wanted to bump this as I never received a satisfactory answer for the reason behavior was changed and it is still something that feels like a UX regression.

Hello Fred McD,

Thanks for getting back to me. First, my computer screen froze (I suspect some interference of a hacker or something).

Anyway, I turned off my computer, waited several minutes, and turned it back on, again. A message came on the screen said I wasn't "signed in." Then, another smaller window came up saying I could "sign in" by clicking on a blue button. But, that didn't work after three tries, so I clicked on the "closed" button. That allowed me very limited access to the internet. A "black" label announcement said that I wasn't signed in - and that my files were inaccessible to me.

It looks like I need a technician, but I presently have no car and I don't know of any technicians who do "House Calls."

I'm also wary of contacting an online technician. One time a year or so ago, I looked up a phone number for Microsoft - and the guy I spoke with had an "Indian" accent. He sort of helped me for a stiff fee. In hindsight, I realized he couldn't possibly have worked for Microsoft - even though he assured me that he did...

Can you or someone on your staff possibly help me. I trust Mozilla Firefox and I'm prepared to pay a reasonable fee.

Thank You, Eric Vollmer

I can't open a particular site i watch in private. I refreshed browser; I gave permissions off and then on or enhanced tracking off then on and neither nor changed anything. The website help desk that i tried opening verified password asked which browser and still it wouldn't open when putting correct information password and user name in. Any suggestions? I didn't do anything different and thought it was the website but i'm member and nothing's changed on their end.

Update to version 96 64-bit just completed. Many websites now experiencing Secure Connection Failed PR_END_OF_FILE_ERROR. Did Help -> More Troubleshooting Information -> Refresh Firefox to go back to all defaults. Open Firefox again, add Menu Bar. Open what used to be home screen tabs, ok at first, but within minutes start experiencing Secure Connection Failed in several websites. Seems to come and go, sometimes a Reload current page restores normal website, sometimes not. Close Firefox, open again, restore previous session tabs, only a matter to time before one or more start getting Secure Connection Failed errors. No extensions, no themes. Browser is now so unreliable as to be unusable. Please assist.

In settings, Start-up, I have the box checked for: "open previous windows and tabs" but it doesn't work. In order to do my work I need the 23 tabs I currently have open to show up again after a reboot of the browser or computer. What gives? How long will it take to get this corrected? Please give me help. Thanks, Mark

I've tried everything and read all the instructions but none work.

Got online this morning, and Firefox "upgraded" to a newer version. Now, I have no home page, no bookmarks, no history, etc. This happened several "updates ago, a few years ago, if memory serves. How do I get all those back? Last time, they apparently sent out a "fix". Thanks,

Mac OS 11.2.3 Tried every tip in the troubleshooting guide. Firefox still does not work. Downloaded and installed version 96 but "Update History" only shows up to 95. Thanks for any help.

Hi I went to my email provider earlier on and Firefox froze saying that a copy was running and to close - which I did. But Firefox will not access any website: just the normal waiting message.

I did a hard reboot. No joy. I tried a download. No joy. I am using Brave at present to access you. Everyhting else, email etc is working fine.

Any advice please.

No websites will load at all. The address looks fine but the loading ends up timing out just like when the address isn't correct or the site is having issues. I believe this started after the last update, I don't remember if it was a Firefox or windows update. I've tried the suggested troubleshooting tips, and uninstalled re-installed firefox twice. All I achieved was to lose my dark theme and previous open tabs.
