Firefox Support Forum

Pretty niche problem, but I couldn't find anyone else with the same kind of problem. Whenever I try to download a file with "%" on its filename, the "%" character gets changed to an underscore. Like say, if I try to download a file named "Skyrim 100% save file", it becomes "Skyrim 100_ save file". Not sure why this is even happening, but it only happens in Firefox. Not Chrome nor Edge.

i have been using Tor.browser as my default web browser on Macbook for months. Firefox is my 2nd, but two days ago, i was kicked out of Tor, cannot download/use it anymore and the reasons given are as follows:

"Tor.browser quit unexpectedly. Click Reopen to open the application again. Click Report to see more detailed information." Ignore Report Reopen (options)

when i have deleted and tried to re-install tor browser, I get the notification that

"Tor Browser quit unexpectedly". No matter what I do

 (I have since done both, obviously & have tried many other things, including trying to Time Travel, which I am not 100% sure how to yet).  the Report states Firefox is responsible for blocking Tor.  how did this happen and suggestions on how to fix.  I have to access Tor to find some pertinent files etc. I have stored there.  thanks

I wish to export, and not copy, a digital certificate so that I can import it to Keychain on my Mac. The only option in Firefox Browser on Mac is to copy, which means it only opens as a TextEdit and cannot be imported.

Any recommendations?

I have an older piece of equipment that I need to communicate with it and the 232 interface will only work through Firefox. I was told I can downgrade the current version to 3.0, which is what I need, but I cannot find out how. HELP

I have not been able to sign in to my firefox account. I recently re-installed windows and tried to log in in firefox but its giving the error "The request was blocked for security reasons". How do i fix it? Help me i have important bookmarks and websites that i don't want to lose.

I am a very long user of Firefox but absolutely hate the migration to an upgraded PC. I was trying to backup my firefox settings/profile to save passwords, bookmarks, etc. When I went through the process of creating the profile, it reset my Firefox settings altogether and now populates my Windows desktop with firefox folders and files (folders like cache2, minidump, startupCache). If I delete the files, once I rerun Firefox, they come back. How do I revert to the typical setup where those files are held in the User area or otherwise? As it stands, Firefox is totally unusable.

Many thanks to anyone who can help.

Have been fighting to get back to square one after an overly enthusiastic VPN system screwed up my browsers. Not just Firefox.

I needed to do a clean install. So I followed the instructions to delete the appdata/mozilla/firefox directory.

I don't want stuff to look the way it was before the install. I just want to try to put things back together to my liking.

Is it stored somewhere else? Is the existence of a backup known?

Why can't there just be a question: "Clean install or Refresh?"

It should not be this hard

Hi, the official Firefox docs recommend copying and restoring the entire profile directory. That doesn't work when restoring a profile created on Linux, on Mac, it seems. Neither for Thunderbird, by the way.

Is there a proper way to do this, or should I experiment with each of the files (databases, configurations, etc.) one by one? Thanks!
