Firefox Support Forum

This particular site (donjon.bin.sh) and others like it have a feature that generates a slightly different image than the one generated by its randomizer, in this case a D&D map for the players that doesn't have the same info as the one for the DM. There is no online version of the player map that can be viewed, it can only be downloaded via the "Player's Map" button (pictured). When I click the button, the pictured dialog box opens up, but no matter what settings I input in the dialog, the "OK" button remains unclickable. There does not seem to be another way for me to download this image within Firefox, since there is not a rendered image on the page for me to right click -> save.

Since the release of Beta version 89.0b3, Firefox Beta on Win 10 keeps reverting back to .0b2. I cannot pinpoint exactly when it happens; sometimes after 'hibernation'; sometimes after 'sleep'. Getting damn frustrating, and I'm not nearly ready to move up from Windows.

How the heck do I track what's going on? All advice gratefully accepted!

I just installed Firefox for the first time and I downloaded a pdf and when I went to access it, Firefox shortened the name of the file to two letters. When I tried to rename it to the full name, it only gave me so many letters. That never happened to me with Chrome.

Since I find the new Proton GUI a step backwards in usability, I plan to defer the inevitable as long as possible by moving to the ESR version (currently V78).

1. How long are ESR versions supported?
2. What is the ESR version release cycle?
3. I plan to try using the -allow-downgrade command line option when downgrading, but the articles "Install an older version of Firefox" and "Command line options" are a bit short on step-by-step instruction. What is the correct procedure / sequence?
4. I have serious misgivings that the result will be usable, given the large difference in version numbers. I have made a backup of my profile. Should I have problems with the downgraded profile, I will presumably have to create a new profile. How can I recover data from the backup profile and import it into the new profile?
5. I am using Firefox Sync and hope that it will relieve me of some of the pain associated with a new profile. I am not syncing History however, because I prefer to keep the histories of my separate Firefox installations on different devices separate. Is there another way to preserve the history from a particular installation?
6. If not, what can I expect from sequentially turning on history sync on my various Firefox installations?
7. Will all history be merged or will subsequent history lists overwrite earlier ones?

Any further advice which might prevent me from screwing this up would be most welcome!

I download anything over a certain file size, a couple of Mb, and Firefox pops up with this error "failed". I then must manually start the download from where it left of and it resumes this cycle of stopping and me starting.

Hi, I upgrade Firefox to 89.0.2 from the previous version. The installer "locked-up" during the installation process. I am using Win 7 on a Dell Inspiron 64-bit laptop (2017) with plenty of memory. Never had problems before. The installer locks and I have to stop it via Windows Task Manager (setup.exe *32). I have reloaded the "Firefox Setup 89.0.2.exe" file several times, reloaded the previous version... no avail. It locks up. I tried to start the Firefox even if not fully installed, using Firefox.exe It stated that it did not close properly and to "refresh", which I did, the program browser started after saying "success", but then stopped responding (screen locked-up) while showing me the usual Firefox screen (i.e. with all my previous opened tabs, bookmarks...) After having deleted the program manually from its location, reloading it several times - the same issues took place. Can someone help, me? Thank you, Ciao, L
