Firefox Community Forum

I originally deleted Firefox by accident and have downloaded it via Microsoft Store. All seems well then after I click on the app to open it, I Get the ‘Windows cannot find C:\Program Files\Mozilla Firefox\firefox.exe. Make sure you typed the name correctly, and try again’ for ‘Firefox’ error how can this be corrected?

Today I needed to reboot my browser, and did so they same way i've done countless times before, but when I restarted it only 10 of the 11 windows I had open before closing it were in the "Recently closed windows" section of "History".Please tell me there's some way to recover that window.I had a lot of tabs open in that window that I need back.Why would Firefox just discard it like this?Like I said, i've done this so many times without an issue.

My option to "Open a specific page or set of pages" has vanished!!!

Originally a page I play backgammon at wasn't displaying properly, my graphics drivers are up to date so I shut down the browser, when that didn't work I was going to uninstall but at the beginning of that process I was given the option to refresh so I chose that instead.

Unfortunately it took me a hot minute or two to realise my browser was no longer opening a specific page it always had done.

Where has that option gone?

05/20/2025 twitch streams stopped working, image disappeared, sound is there. Also working videos that are on twitch, not streaming. In windows 10 everything works.

I can't get my video chat mode to work on facebook. When I move my cursor over the camera icon I get the circle with the slash through it which prevents me from connecting.

How can I get my "Bookmarks" and "Extension" loaded on my new computer. I've loaded Firefox, signed-in, and completed the "Finish Setup"; but they haven't appeared.

was Windows 10 Pro, now Windows 11 Pro on replacement laptop (old one is not operational). I can't get my profile into Thunderbird because (presumably) I'd backed it up using my cloud backup service (and forgot that most of the time it's incremental), with the possibility of a straight copy from the old SSD if it's not fried.

How can I at least retrieve the data in there, (and/or convert it to a readable format) i.e. emails, that are in the Mail folder, including Local Folders? Some of that goes back to early 2000's, and some accounts that I no longer have. It's probably better to have most of that out of Thunderbird anyway, since my profile is ~99GB on disk.

Currently I have at least 7 active email accounts, and that fluctuates with .edu addresses. In the profile IMAP Mail folder, there are 20 .com account folders, a few of which are inactive or from changes, and a couple from setting up my main account just to see if that would link up with the associated files in the old profile (not). I can't tell what they all are except for those for which I'd made subfolders under the IMAP Inbox.

So since I don't only have 1-2 accounts, this is a big deal, and having to keep multiple browsers/private tabs open is not easy to work with. I'd even tried the Firefox Containers as a temporary work-around, but I'm having troubles with that.

Any help is appreciated! I can't get anything done, and the new laptop doesn't even have all that I need set up yet.
