Firefox Community Forum

I did a windows security scan yesterday and it found a trojan in the Users\appdata\local\mozilla\firefox\profiles\c4h...\cache2\entries. Detected: Trojan:Script/wacatac.H!ml.The file is a containerfile. I tried removing it few times but it keeps coming back. This has made me feel uneasy even though I believe it to be a false positive. I've done 3 scans now and it always finds the same file. When I try to look for the file in the folder it's not there, so I can't upload it to virus total.

I often work with dozens of tabs open in Firefox, and I notice a drop in performance after a while. Are there specific settings or extensions you recommend to optimize Firefox for multitasking?

I’ve come across some tips for general browser optimization, but I’d love to hear from the community about what works best specifically for Firefox.

I've tried everything under the sun that I've seen other people suggest for this problem like custom scripts and altering the config but no matter what I do Youtube just doesn't load videos AT ALL any other video streaming site works wonderfully like Netflix and Youtube works on explorer just fine if anyone has a solution or even just an explanation as to why this is even happening it would be greatly appreciated.

I would like to reiterate everything said below. This needs to be a standard feature. This seems like a no-brainer and should be a standard function on any browser. It only shows that Mozilla is getting left behind, even Edge has this feature, what makes it worse...IE had this feature and that is considered ancient tech now. from: kenmendell Now that I've got you and we're on the subject, Firefox seriously, MOST seriously, needs to bring back the "Bookmark All Tabs" command and have a "Save All Tabs" command of its own. There are no third-party apps and Add-Ons that do this very well anymore or at all, the older ones that used to do this no longer work well or at all. Firefox needs them in the browser to stay. It's never been the same without the "Bookmark All Tabs" command and trying to "Save All Tabs" the same way you would save a single page with "Save Page As" is frustratingly impossible to do. Any older Add-On or program that did this no longer works well or at all and hasn't for almost a decade or longer. It needs to be a standard function of any advanced browser. Firefox needs these functions as the normal standard. So, bring this up with your design team as an imperative because my having to migrate to these other lesser capable browsers the way others have doesn't appeal to me when Firefox should be a decade beyond their design and development, especially for functions that shouldn't be difficult hurdles for any modern browser to have.

New computer, W11, completely updated. The old SATA SSD was removed from old PC, had W10 on it and that had FFx 133.0 installed; successfully transferred the bookmarks to another W10 PC but not the Passwords/logins. Transferred all the information from the Mozilla folder (per Firefox/Mozilla help) to a USB: plugged it into my new computer and did the same transfer of the Places, Key4, logins, and favacons to the new computer: no change. Just finished uninstalling FF and removing the Mozilla file from App Data, then doing a complete reinstall; then added the old places etc. to the new install. Nope, didn't work. So what's going on with FF and W11?? Is there a solution? I have been with Firefox now for over 10 years and have never had these kinds of problems moving my information.
