Firefox コミュニティフォーラム

I had a ton of saved tabs and groupings of tabs. I closed what I thought was my only open Firefox window then downloaded and installed the most recent Windows update. When I rebooted, I did not realize I had left a Firefox window open with a single tab. That Firefox became my default and I lost all the tabs I had. Is there any way to get those tabs back? The tabs I had yesterday, 1/22/2026 are the ones I need.

Hi I keep getting this error on Firefox. I did disable all my extensions prior to this image shown to see if it was an extension causing an issue to no avail. I also looked for an update for Firefox and saw it was up to date. I also attempted to refresh Firefox which was a successful refresh however the error persisted. After refreshing I fully uninstalled Firefox and then reinstalled however the issue persists.

This error is shown however if I refresh the page sometimes the page freezes as if it lost connection and sometimes it reloads as per normal with the video playable.

Hello.

1. How to save a tab group without closing it? 2. How to make individual tabs in a tab group permanent? (So when you close a tab group only the permanent members are preserved.)

Hi I have a website that suddenly started crashing. Hope you can help solve this problem. The problem is on Nettavisen.no. Using Macbook Pro. This has never been a problem before today. Kind regards Sonja

This image is one of a series of similar messages I get. Incredibly, this has even after a 2-step verification is competed.

I have no problem with Yahoo in Chrome. No problem with the Yahoo email mobile app.

I am not a Chrome fan, but It is not unusual for me to have to use Chrome to avoid random website behavior issues with Firefox.

Dell installed a command update and immediately afterwards, Firefox would no longer open, either from the taskbar icon or from settings/apps. I just get a couple of seconds of the blue cycle icon and then nothing, no error message, just nothing. I did download/install repeatedly but I don't get beyond the download screen - as soon as it's 100% downloaded, that's it, no welcome window, nothing. Thanks

When using Firefox on a Mac, how can we set the Mozilla VPN to one specific country for one tab only? There are instructions for doing so, but it's only applicable to Firefox for Windows.

Several websites are not loading their content since yesterday. YouTube has a message "Try searching to get started" and even when I open a video, it won't play. X.com is not loading content in the pages. So far it's those two.

I have Firefox reinstalled, it is not syncing bookmarks, history. I tried to import booksmarks from edge but it could not find the file or said it does not have any bookmakrs on it which was not true.

Why am I seeing this message on windows 11 and not on my windows 10 machine. I am still using th internet on both machines on the same network but you tube on W11 is constantly having to be refreshed. BRAVE works fine.

I reinstalled Firefox on my laptop after it crashed. I also have Firefox on my iPhone. The profile there is up to date. How do I sync that profile to the laptop installation?

I set the about:config settings when I got the new computer early last year. It's been working fine. Suddenly, searches are popping up again to the urlbar.

browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar is still set to false. Keyword.enabled is still set to false.

I see a couple of site references to browser.fixup.alternate.enabled, but it doesn't exist.

How do I get FF back to proper search in the search bar?

I have entered in exceptions for a web page that Firefox continues to block....I have gone through your steps 4 times now...one time out of 4 you actually let the web page through....since then you don't again...what is wrong with your system? as I am not receiving a download link from the intended exception due to the fact you are not honoring it....
