Firefox supportforum

System : Linux Mint 20.2 FireFox : 91.0.1 (64-bit)

Plugins/extensions "Hoxx VPN" and "SetupVPN" seems not to work anymore This is since FireFox 91.0.1 It takes a long time (about 30sec) connecting to the VPN, with no result. (no connection)

Both say something like : Result

<country> (SERVERS) 3.11.4 In some cases VPN extensions are not enough to bypass the firewall in your network. Extensions have only limited permissions on your computer and have limited capabilities.

We highly recommend to download our desktop client. It uses a very sophisticated VPN software and can bypass most of the firewalls.

I'm a web designer, trying to move away from Chrome because of privacy/security issues. I'm also 63 years old. My eyes are old. The text size on the tabs and bookmarks is very difficult to read. I don't want to increase the size of everything else - ***just the tab and bookmark text***. I've tried the fix seen elsewhere in the community for this question, but that doesn't change the size at all. If I increase the size, say by Zoom, that's a problem with my page layout. Can anyone help, please?

I'm on a Mac, but using an LG monitor, so no Retina display.

I used to use Adobe flash, but noticed on Google it's no longer supported

FF suggest using "shockwave flash" but can't seem to find it, any idea's / suggestions please?

How to install Firefox Developer on Linux (Ubuntu)?

I tried the manual way:

but it does not seem to work for me.

I keep changing my browser default search engine to "Google" and it works initially. But when I close Firefox and reopen the program it defaults back to "Browser Default." How do I make the change stick?

windows 10 downloaded some updates yesterday & now some websites that I used frequently say access denied. What can I do to correct this? I'm not very technical.
