I want to install an unsigned addon that I made. I can load it temporarily via about:debugging, but I can't actually install it. Maybe I'm doing it wrong, I couldn't actually find any explicit instructions online, so I packed the files into a zip with a .xpi extension, and tried dragging it into the about:addons page. I get a "the addon could not be installed because it appears to be corrupt" error.

After reading this thread: https://support.mozilla.org/en-US/questions/1134589, I went and installed the developer version of Firefox Quantum, but I'm having the same problem.

So after I updated to firefox q it keeps deleting my history after a month.

I installed fresh firefox and new profile in November, but if I go to my history I only find February, so November, December, and January is gone. In settings I have it to save my history but it still delete everything older than a month.

Hello,

Yesterday my Firefox was working just fine but today it doesn't play any sounds. I tried everything listed here https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues. I also tried "Refreshing" Firefox but nothing changed.

It's only Firefox, Google Chrome and Spotify work great.

I'm on Ubuntu 16.04 LTS and the Firefox version is 59.0b14.

Sir: I run an Imac with El Capitain OS installed. I recently downloaded the latest Firefox Quantum upgrade to 59. Suddenly, my Yahoo search engine no longer works. This started a couple days ago. Any ideas as to why this is happening. I've been using Firefox/Yahoo for years with complete satisfaction. Thank you for your time. Dana R Gregory
