Firefox Support Forum

Due to a recent major security breach I started changing all of my passwords on my main desktop, I did not have sync on at the time. I then opened up my work laptop (again unsynced) and decided I should really use the sync feature to transfer my 500+ passwords onto my laptop for when I travel.

When I got home that evening, I turned on the sync feature on my main desktop, unfortunately it pulled all of my compromised passwords from my laptop and overwrote the ones on my main desktop. Is there anyway to restore my pre-sync passwords and ensure that they get transferred to my laptop instead please.

Hello,

I have been facing this issue when accessing Google Drive using Firefox, after selecting a file and clicking on "File information" option the "Details" and Activity" tabs simply don't load, as you can see in these screenshots.

Also, I found this thread also here on Mozilla Support from two years ago that reports the same issue. Apparently the bug was solved but ended up returning in most current versions.

I opened the current thread just to report this bug again. Thanks.

EDIT.: Another user reporting the same, his thread was archived: https://support.mozilla.org/en-US/questions/1422875

Firefox was logged into my account and synced before migrating computer to Azure AD. After installing and logging into the fresh install of Firefox, there is no data associated with the account. It looks as though it was created today, even though I logged into the pre-existing account. I even have emails to this account from over a year ago.

Any way to recover?

Dear friends, I receive fake virus alerts from baseauthenticity.co.in. How can I stop this? Many thanks in advance.

Can I have more than one bookmark toolbar at the top of the screen? I am a teacher and I have at least 12 maths bookmarks I would like to display as well as my standard / personal bookmarks.

I went to settings and then to privacy and security and tried to find auto fill to remove credit card info. I couldn't find the setting the browser told me to find.

In early May I started having problems with Google on Firefox. Sometimes the Google home page won't load up at all. Once it does load up sometimes the searches work, sometimes the search just times out and goes back to the empty search bar, also when I click on links to websites they time out too. If I go straight to a bookmarked website, that seems to free things up and the next Google search I do will work. I've uninstalled and reinstalled Firefox but it doesn't make any difference. Google works fine on Chrome and Edge. Any advice would be gratefully received - please note I'm not technically minded! Thank you.

When I try to open a what may be a link in a page, which should bring up a PDF file, I think, I get the following:

Firefox Can’t Open This Page

To protect your security, api.medicare.gov will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

When I click on the Open Site in new Window button I get a new window with the following:

message "Unauthorized" context {} code null

I am trying to add an mp4 video to my website using the following code:

<video width="320" height="240" controls>
  <source src="images/###.mp4" type="video/mp4">
</video>

where ### is the name of the video file. I get the following error message:

"No video with supported format or MIME type found."

In the console the following is displayed:

"Media resource http://127.0.0.1:5502/images/###.mp4 could not be decoded. video.html All candidate resources failed to load. Media load paused. video.html Media resource http://127.0.0.1:5502/images/###.mp4 could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_METADATA_ERR (0x806e0006)"

Runs just fine in Chrome and I have no pop-up blockers installed. Autoplay is set to be allowed for all websites.

Windows 11 version 23H2. Firefox version: 126.0 (64-bit)

As title- Cannot download for example webm format, but jpg is okay. cannot install any addon, theme or anything. DRM didnt install as well. i was trying reinstall, refreshing browser, rebooting.

On Edge or other search engines I've been able to highlight, copy and past a web address where the pasted result is a clickable link to the website, but this doesn't work for Firefox. I have looked through the settings and other questions online, but found no solution, from what I can see people more often ask about the opposite issue to mine. Is this a limitation of the search engine or am I dumb?

I'm trying to import a password csv file generated by Roboform into firefox password editor. I've exported the csv file from Roboform but when I try to import to the Firefox password page I get: "Incorrect or missing column headers. Make sure the file includes columns for username, password and URL". The csv file does have column headings. Is there a way to do this?

My website is shown as insecure. If I open it with Chrome, it is okay. If my girlfriend opens it from her computer with firefox, it is okay too. What is wrong here?

I just uninstalled firefox for personal use at home (Still use it for work).

I tried to change now given chromium is about to be neutered with ad blockers etc.

This was my feedback - Extremely disappointed and non-functional profile option/s. Wanted to provide feedback that hopefully someone sees, as there is going to be a mass migration to FF soon and if they do NOT fix the below, people will give up fast.

"There is no basic multi profile support like in edge, chrome etc. which is shocking.

about:profiles is completely useless, because once you sign in with the same firefox account again, it just syncs to the same profile.

Firefox MUST have multiple profile support under 1 login, not combine them. The thought of having to sign up a completely separate second account/email for a second Firefox 'account' with a second 'mfa' token just to separate personal and work is ludicrous.

I want to sign in, pick my profile as personal / work and then it syncs my diff favourites, plugins etc. per profile for work or personal depending where I am, NOT SHARE them all on 1 login. This is not possible and a huge disappointment considering these features are considered basic in other browsers."

Until firefox does this, it is unusable for multi work/private profiles and signing up a second Firefox account is just silly.

When I open poges now I see often "Firefox darf diese eingebettete Seite nicht öffnen" maybe similar to "Firefox can't open the imbedded page"

I can't see my own music tracks posted on x.com! That's a kind of fraud! What are you doing? At SAP I have to use Edge on Linux already cause you are doing a very bad job! WTF is going on? Are you doing anything or just breaking things?

As the title says, it is very slow with Ublock Origin. I have refreshed Firefox and without Ublock it obviously works but I would like to keep the extension because it is the only one that works with Youtube Ads right now.
