How do you access Mozilla VPN after you have logged into firefox account - it only shows how to download and I have already downloaded it. I simply want to turn on the VPN and select the location but no instructions are available for this or at least the instructions are not clear.

"Show all bookmarks" seems to have vanished. How can I get it back, so I can back up my bookmarks? Or is there another way to do that? (Should have been clear about this: no problem finding the library symbol, opening the bookmarks toolbar or opening the bookmarks sidebar. However, the "show all bookmarks" entry is missing from the sidebar. The main headers on the sidebar are "bookmarks toolbar", "bookmarks menu", and "other bookmarks". "Show all bookmarks" is not a header and I cannot find it in any of the others. If I search for it in "search bookmarks", nothing emerges.)

Hi there, I would like to “generally accept all cookies” for future surfing through the internet. I found this description (see below), but it doesn’t seem to work (help might me older before latest browser updates), could someone tell me how to set Firefox to accept all cookies? Thank you.

1. Click the Tools menu from the top toolbar. 2. Choose Options. 3. Click the Privacy tab. 4. Under "History" select "Use custom settings for history" from the drop-down menu beside "Firefox will." 5. Ensure that the checkboxes for "Accept cookies from sites" and "Accept third-party cookies" are both checked. 6. Click OK.

Everytime I open Firefox to search I get the following response:

And I have to go through a captcha process to get through. Oddly enough, I NEVER get this problem if I search (for exactly the same addresses) from within Google Chrome. Is this a Google scan to try and force back to Google Chrome?

Dark Mode used to work beautifully in Firefox. Today it stopped working. I can choose Dark Mode in the settings page, and the settings page itself then uses Dark Mode. But Dark Mode does not work in any of the other pages, only the settings page. I think it must be a flaw in an update that was installed automatically today. (September 7, 2021)

Is there a way to uninstall this update and go back to the previous version. Dark Mode used to work beautifully and Firefox was my favorite browser. Can someone help? Thanks.
