Hallo zusammen,

ich kann meinen Firefox nicht mehr aufrufen, weil er wohl nicht kompatibel mit 133 ist. Es wird empfohlen zu deinstallieren und neu zu installieren. Aber dann sind meine Favoriten, Lesezeichen und Passwörter weg. Ich kann sie nicht sichern, weil ich keinen Zugriff auf die alte Version habe. Wie löse ich das Problem?

Viele Grüße Annette

Hello everyone,

I can no longer access my Firefox because it is probably not compatible with 133 (see screenshot). It is recommended to uninstall and reinstall. But then my favorites, bookmarks and passwords are gone. I can't save them because I don't have access to the old version. How do I solve the problem?

Best regards Annette

For about the last 2 months, when I either get a notification that an update is available or I manually check for updates, both Firefox and Thunderbird are stuck in "Downloading updates -- 0 bytes" on 2 Windows 11 computers. Eventually, like a half an hour to an hour later, the update downloads and I can install the update. This has been going on for 2 months now. As a 20 plus year user of Mozilla and also a long-time financial contributor, this problem going on for 2 months is getting old. And yes, I have checked my antivirus and firewall. Is Mozilla aware of the problem and is there a solution?

Presently 142.0.1 (64-bit) installed; previous updates/downloads had no problems.

Now, however, going to https://www.firefox.com/en-US/?utm_campaign=SET_DEFAULT_BROWSER and attempt a download results in this (image).

Any solution to this?

Thank you.

I am currently using Windows 11 (64 bit). I have installed Firefox in a separate drive instead of Local C to save space. Now that I have done so, the automatic update fails often which causes me to try and find the custom installation on the Firefox download page. I use https://support.mozilla.org/en-US/kb/custom-installation-firefox-on-windo... page to try to find the correct installer.

Unfortunately, the download page that I was directed to, I can't seem to find the custom installation setup. When I click download, it keeps giving me the automatic Firefox Installer and proceeds to add Firefox on my C drive rather than the Mozilla Firefox Setup Wizard.

Can someone kindly direct me to where I can download the Mozilla Firefox Setup Wizard to update Firefox?

В России блокируют Firefox, по этому авто обновления не устанавливаются, я бы хотел получить ip и url серверов от куда скачиваются обновления. Это поможет обойти блокировку и восстановить работу firefox в России

bold text I am booting up an older Windows 7 tower computer and wish to know how to update both Firefox and Thunderbird? The update popup seems to be stuck in download phase.

I accepted an update to my computer and immediately Firefox could not load, the exe file is missing. Again I use windows 7 . May have lost all passwords and bookmarks. Please advise.

From "About" on the Firefox menu I am trying to download the update from 145.0.2 but it is stalled at 27.1 of 31.3 MB. The little pair of spinning arrows icon just keeps spinning without making any further progress. I'm on a 2020 iMac running Sonoma 14.5 My internet connection is still functioning. I'm wondering what I should do. Is there a way to just cleanly stop and start over? Or stop and continue.

How should I fix the frozen browser. Firefox updated ok from another user account on this computer, though Firefox has always updated for all accounts on the computer when updated from any of the accounts. The installer tool got caught in a loop to install until it froze the browser on the third retry. What should I do?

I'm running Firefox 139.0.1 on Mac Sonoma 14.7.1.

Since FF V138, I've had this extremely frustrating problem where, approximately once a day and while the application is still running, Firefox seems to either auto-revert to an older version' 'or otherwise mess up the installation files. I don't get any notice this is happening until I try to open a new tab and it brings up the "You must restart Firefox" notice. When I click Restart, it pops up with "You've launched an older version of Firefox, so you won't keep any of your bookmarks because that would be unstable" error.

The only way I've found to fix it is to redownload the most recent install files, which, after the fresh install, will allow me to keep using Firefox with my bookmarks for the next 5-6 hours, before the whole process starts again.

I theoretically have auto-updates off; my settings are set to the other option, "Check for updates but let you choose to install them". Doesn't seem to make a difference. It only does this on my Mac; the FF install on my Windows machine works fine.

I really want to keep using FF. It's my preferred personal browser. But this is really messing with me! I was hopeful that 139.1 would fix it but same issue, so far.

I read there is a need to immediately update Firefox. I down;loaded it, but got a message that a newer version exists...? Also, it shows my latest update was 11/24. I use auto updates and recall one much more recently.(in fact I found the new tabs annoying) I am perplexed.

cannot update browser. Currently using Linex Mint, #139, but latest is 150. As stated above, when I try to update, says browser update disabled by organization. Do not understand, I never authorized disabling browser updating.

Hello, I am still running an old WIn 7 media center because I have applications I need that are no longer supported elsewhere. Firefox ESR has been working just fine up until the most recent update - which repeatedly fails to install each time I start Firefox. Is there a location where this update resides? If so may I know this location and procedure to eliminate this errant update? Thanks!
