Hello, In summary, I am a total beginner and just need help making the right-click menu appear properly on sites and such like it used to before I screwed up some random setting. If that's not doable, then could I get some help to try and see if I can restore a backup of older FireFox settings that predate my messing up the settings or something? Basically, I was exploring various settings in-browser in FireFox and at some point somehow changed something that suddenly prevented the right-click menu from appearing when I right-click on anything. I also was changing things in the settings of an extension called "Sideberry" that I use to organize tabs, so whatever I changed that is stopping me from right-clicking properly might be in that extension's settings rather than in the normal browser settings; I am not sure. I tried changing "Use native context menu" (in Sideberry settings) from off to on and vice-versa, but turning it to be on just prevents me from seeing the extension-specific right-click menu when I right-click in Sideberry. It doesn't make the normal browser right-click menu that you get when right-clicking websites themselves come back. Thank you very very much in advance! I hope you have a wonderful day.
