As soon as i start my computor with firefox i get this message: Warning you have virus. You must install re-captha-version-3-49.top. What is that? I have norton and norton says no virus. What shall i do?

Well, basically that. On normal browse ( no incognito ) tabs will re open if I re-launch firefox, even with the "Open previous windows and tabs" option off.

Am I missing something or is it normal ?

thanx

When I restart my Windows 11 Asus ProArt PC or my browsers reopen, the positions of my tabs will shift around. Sometimes the last open tab will move into position one from wherever it was. Other times the repositionings seems random. I had an issue where I needed to reboot 3 times and in one of 4 windows a huge chunk of tabs repositioned in reverse order. I want certain tabs aligned next to others for my workflow. This doesn't happen all of the time if I have been in a window but it happens more often than not.

I have my browsers set up with Tab Session Manager to open one tab next to another. I also made a change a while ago to where if I type in a different website within a tab it will open within that tab instead of opening a new one. I only open a new tab if I want to.

I also find that despite having different sites having been opened in the same tab once I come back to a new session the previous tabs I'd opened there are gone and only the new one remains. That is less of a problem than tabs simply repositioning themselves wherever they choose. But if that is a clue to what is going on, there it is.

Hello,

I just got a new Macbook Air and I am trying to sync my bookmarks and preference etc., from my current Macbook Pro. I read the help articles and one thing I cannot find is a "Sync Now" option on the Air. It is not under the menu icon list. I signed out of the Pro and back in. The user and PW are the same on both laptops. Hoping you can help.

Firefox has been my default browser for longer than I can remember. Over the years, I have maintained a significant bookmark file for work. I recently purchased a new computer, and my zero bookmarks from the new computer have replaced all of the bookmarks that I had in my old browser. This is a bookmark file that has successfully followed me through multiple computers and even my ios devices. And now it seems to be completely gone. I've looked at the places.sqlite files, and the largest one is 20MB and is in my current default profile, but it is dated today. That makes no sense because I do not have any bookmarks on this older computer, and my new computer doesn't have any either. The bookmarks have also been completely deleted from my iPad, but miraculously are still on my iPhone (evidently I had signed out of Firefox for iPhone at some point so they do exist somewhere.) The thought of trying to rebuild my bookmarks is nauseating. My only thought is to sign out of the browser on all devices, then sign back in and sync on the phone. Would that repopulate the main file with what's on my phone? Any other ideas?

My Firefox browser keeps autofilling username on one important website and it is preventing me from accessing that website. Website indicates that this username is not valid. How can I stop this?

The File -> Page setup option used to be visible by default. Now I have to dig into the "hazardous" about:config menu to enable it. This was available by default for years (decades?). Why is it now hidden away from average uses who may not need or want to mess with the custom prefs? Feels like Firefox is becoming more difficult to use rather than easier.

print.prefer_system_dialog and print.show_page_setup_menu seem like really basic features that the average user would want by default. Both require a trip into about:config now.

Hello! I need some help. Every since 4-6 months ago, Firefox has been extremely slow when I boot it up at first, with some page load times taking more than 10 minutes. Some fixes have seemed to work, but they never work permanently. From my testing, it is not the result of any extension and the issue persists in troubleshoot mode. What has not helped my testing is that, after enough restarts of Firefox, the problem goes away and web pages load quickly, so this has caused some false positives. Has anyone else had a similar problem they were able to fix? Should I try uninstalling Firefox and reinstalling it?

When I upload an image with Firefox, it typically shows a red tint. I've seen similar reports from decades ago so I disabled `gfx.color_management.mode` in `about:config`, but that didn't help, even after restarting the browser and the computer. I disabled a couple of related settings, but that also didn't help. What else could I try?

When trying to set up proxies in firefox, I typ in about:config i accept the risk and continue and get this message: Changing these preferences can impact Firefox performance or security. And I cant go any further. Please advise.

After updating to Windows 11, all my Firefox webpages backgrounds are colored black even after choosing a light theme which only changes bookmarks and toolbar to white. I want white background like my old Firefox ?

Hello Mozilla Support, I want to ask how to turn off suggested websites on my home shortcut. I searched on the internet, but everything I tried didn't work.

Machine is Windows 10 with a Logitech wireless keyboard. Latest Firefox browser. Not always but sometimes when using Firefox browser to log in somewhere or enter data on some web site, I'll get an incorrect entry for a key stroke. e.g. I enter a 0 and get a 1. But if I enter a 1 I get a 1. So far the error key has always been different.

I've tested things by launching a notepad or Word document and entering the character and in those all works fine. But go back to Firefox and I get the error again. What I have to do is to close and re-launch Firefox and so far this fixes things. It's an intermittent problem which forces me to keep another browser on the machine and ready. Imagine entering a password when all of a sudden you type 'X' and it gives you an 'E'. Really frustrating!
