Diễn đàn hỗ trợ Firefox

I accidentally downloaded a newer version of Firefox on my iMac but it is too old to run it. Now I have no way to download an older version that I use to have. Don’t have any suggestions? Thanks

Using iOS on Mac Mini desktop, I get no sound on democracynow.org but on the iPhone the sound works fine. Most other streams/videos have fine sound but not imdb.com on the desktop with iOS but again, fine on the iPhone.

I have over 100 open tabs spread over 4 Mac desktops. I can no longer access ANY of them after upgrading to macOS Tahoe 26 and installing ESET Cyber Security Pro. I've used ESET with Firefox for many years without ANY problems. But now I have to choose between uninstalling ESET and being unprotected in order to use Firefox AT ALL. Every single webpage is blacked out with the message below. ESET support says that Firefox needs to issue an update to fix this problem.

I need to enlarge the font on the bookmarks toolbar as I have a visual impairment. I can find ideas for the regular toolbar, but not for the bookmarks toolbar...oh, and I am working on a Mac.

Thanks in advance for any help.

Regardless of website Accordion controls don't work / open to show information. These controls work fine in other browsers and work fine on the same sites. Is there a setting I am missing. it also works on other macs I own. Thanks

I have looked over this computer high and low for any profile files in every way recommended on this website. I can't find it, regardless of what I put into terminal or what settings I change. This was a problem before the update to tahoe too.
