ich kann auf Firefox nicht mehr zugreifen. Ich habe firefox deinstalliert und anschliesend neuinstalliert Die Fehlermeldung lautet stets: c:\program files\mozilla firefox\firefox.exe konnte nicht gefunden werden

Ich habe Windows 10 64 Bit

I started receiving a message that "Firefox is already running, but it is not responding...". Tried Task Manager to "End Processes" - Didn't work (still getting the same message on start up). Tried to uninstall and reinstall Firefox - Didn't work (Getting the same message when I attempt to reinstall. About to give up and go with another browser. Can someone please tell me how to get rid of this message and reinstall and start Firefox? I would REALLY rather use Firefox. Thank you!

I have been trying to install Firefox on a Windows computer running Windows 10 Pro. I have two users on the computer. I have installed Firefox successfully on the main user but every time I try to install for the second user, it does not install. it says it failed and leaves a strange icon on the desktop which, when I click, it deletes the file. I am not sure why. I have installed the same on 11 other computers with two users and no problem with those ones.

So Im trying to download a 1.19GB file and get 300mb/s ethernet speed using speedtest.net/ Now normally from my experience its never taken longer that 10 sec to Download such a file. Although since today, either Firefox or my pc has decided to limit download speed to 90kb/s which means this is going to take 3h or so to download. I use Windows 10, don't have a metered plan enabled or any other wifi/ethernet speed limiting things, and no third party security software. Anyone have any ideas why this could be happening? Many thanks in advance

Firefox can not be installed on Macbook Air with M1 and Big Sure, installation can onely be done temporarily. Each time, i want to start Firefox i have to install it again. Is ther any solution? Thank you.

This issue is occuring for couple weeks now. When i click download nothing happenes. No matter what i try to download, it wont work. I do my downloads in another browser :D Why is that happening? I did reset firefox by the way and there were couple downloads and then it broke again. I have this add on saves backup automaticly and here we can see there is something wrong because it cant save the file.

I've been using Firefox 63.0 for quite some time and had dozens of websites open. I referred to these websites frequently. After checking some emails this morning, I decided to RESTART my laptop. It turned out this was a HUGE mistake!! When I went to "Recent Items" as I usually do to find the Firefox link, the only version available was 70.0.1. Not only was 63.0 NOT in "Recent Items" I could no longer find it in my Download logs. I had chosen NOT to begin using version 70.0 because there was no mechanism to move my open site from 63.0 to 70.0. HOW DO I FIND AND OPEN 63.0 OR, ALTERNATIVELY, GET 70.0 TO FIND AND RETAIN THOSE SITES I HAD ON MY 63.0? I should note that ALL MY PASSWORDS where required were stored on the 63.0 browser and are NOT present when I use the 70.0 version!!

hello there, after i download and watch a movie with a subtitle i dont seem to be able to access them later it says files missing or moved and have search my downloads location, everywhere i couldnt find em ......please help

I tried to change some things in about:config which resulted in websites not working properly and reverting the changes wouldn't fix it, so I had to do a refresh of Firefox. The sites work like they used to now.

I'm still confused about Firefox Sync's functionality because when I set it up to sync my tabs it never wants to do it, but immediately after the refresh it downloaded all of my Add-ons right away, which was nice to see. However, my settings/options from those Add-ons are missing, like my uBlock filter lists or various Tampermonkey user scripts.

Is there any way I could recover the Add-on settings from the profile backup which the refresh created on my Desktop? There's a folder called browser-extension-data with some other folders inside, but they're all empty. I tried looking for it myself but couldn't find solutions. I also have a complete profile backup I manually made just before I the Refresh as a safety measure if needed. Thank you very much..!

После очередного обновления снеслись все дополнения. При попытке установить что-либо появляеттся значок загрузки и на этом все. Значок может висеть сутками, но устанавливать ничего не желает. Как это вылечить?(

My former Firefox browser has been replaced by Yahoo (I think my granddaughter "accidentally# Numbered list item" did this)....I desperately want my old Firefox back. Please help me. Thanks!
