Today, I was setting up a new computer and found that my favorite extension, 600% volume booster, has been removed from the Firefox extension store. I looked into it and I found that apparently the extension was injecting aliexpress affiliate links into pages without telling the user. Unfortunately, this extension is the only extension that works for me. I opened the extension up, and I believe I found the malicious script and commented it out. The extension seems to work fine with this function removed, and I found that it was also messing with TikTok video playback, and issue I had been dealing with for the past few months.
My question is, can someone who knows more than me about javascript take a look at the extension to ensure that I am not missing something obvious in the extension that is still a security risk? I have checked almost all the firefox volume booster extensions I can find and I am not able to find one with the compatibility that this one provides. I have a backup of the original untouched extension if that helps.
After a bit of searching, I found this extension that looks suspiciously similar here
