When visiting the "support.mozilla.org site, third-party translantion add-ons(such as "Immersive Translate") can't work. It says "can not read or change data on this site". I want to translate it on the same page rather than skipping into a new page. However, it can work on the "www.mozilla.org" site. When visiting on Chrome, there is not a problem. Is that site just privileged on Firefox ?

I recently came across a webpage that is made to look like a message from Firefox letting you know you need to update the browser. Where should this be reported? I'm sure this is some malicious download though I have no way of checking.

Hello, I closed my browser, expecting it to save my current tabs as it usually does. When I reopened it, the tabs were gone. They were important for me, and some of them were pretty old so I can't find them in my history. I tried checking the "recently closed tabs" option, it didn't help. There was also no option to restore the previous session. Can you help me restore my lost tabs?

I've migrated to Firefox from Chrome and am getting everything as close as possible to my Chrome setup. This is a usability issue when I zoom on an image, that has a larger version. Chrome allows me to zoom to the full extent of the image, but Firefox screen shakes and doesn't allow the same detail. Screen recording and links below.

Hi all,

I feel like this is a problem that must have been experienced and solved a thousand times... however I've tried all the suggested fixes I can find and the problem still persists.

When I load Firefox the pages take ages to load. It doesn't matter what the page is, it takes ages, except that about: pages load fine, no problem. When I say pages take ages to load, I mean that everything about the page takes ages, not only the next, not on the images and other content etc, everything. This only started happening today and I only created a new profile a month or so ago. I don't have many tabs open (maybe 20) of which 9 are pinned. I do have lots of extensions installed.

I've tried troubleshooting/safe mode, that makes no difference.

Private browsing and loading another profile are fine, they don't have this problem.

I've cleared all cache and data, cookies, etc, including startup cache.

I've deleted the content-prefs file, and removed places files.

I've tried disabling and enabling hardware acceleration.

I've tried disabling TRR.

Probably some other things too, but so far nothing has worked.

Suggestions please! :)

Hi there,

On the 23. of Mai I first noticed that I am unable to download any files whatsoever. I tried downloading .exe files and also a .csv file. When I try to download one of these files it appears in the downloads window but immediately goes to the status "Failed". Any retry fails as well.

The same thing goes for extensions. I cannot download any extensions or plugins using my Firefox browser. Since I reinstalled Firefox I can now also not use Plex because Firefox can't install the required plugins.

I will attach screenshots of all the errors I get.

All of the above worked when I tried it on the Edge browser.

Firefox version: 126.0 Windows 11

Things I have tried to fix the issue:

• Use the network connection from my phone instead of my home network
• Disable firewall and windows defender
• Reinstall Firefox
• Refresh Firefox
• Downgrade to version 125.0.1 and 122.0
• Reset router to factory settings
• Flush dns
• Restart PC
• Manually delete profile folder
• Delete temp files
• Change download destination
• Disable "Block dangerous and deceptive content"
• Troubleshoot Mode

Is Firefox using some other temporary folder for downloads?

Any ideas on how to fix this issue would be appreciated.

Thank you.

Hello! I installed Firefox about a year ago, and for the entire duration it seems about 60% of the time the default fonts on various websites look weird (bold?). I have tried uninstalling/reinstalling Firefox, clearing the cache, etc. See attached images for examples. Help!

I am unable to sign into the 7plus.com.au website.

I have tried creating a new profile in Firefox (firefox.exe -p) but I have the same issues when using the new profile.

When I go to the website, the 'sign in' button does not respond, nor does the 'Register' button. When I click on the 'Connect your TV' button and enter my credentials, I receive an error message:

Failed to sign in. Please try again later (error -1)

I do not have these issues if I use another browser, so this leads me to believe that Firefox may be the issue.

I realize the website developers may also be at fault here, but it seems odd that other browsers work, but Firefox does not.

If anyone can offer any help or advice, I am all ears, thanks.

I had to restore Windows to its initial settings. I lost all my programs because of this, including Firefox. I reinstalled the browser, logged in to my account (which is synchronized), but instead of recovering all my bookmarks I got nothing. Empty bookmark box. What's worse, they were initially available on the mobile device, but they were also deleted there (both from the browser and from the smartphone). Firefox restored history, add-ons, but not bookmarks. Is there any way to recover these bookmarks?

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.

My PC froze and had no choice but to reload win 10. After doing so I had the choice to download win 11 for free which I did. When I download Firefox all of my bookmarks were missing. I have tried to follow your instructions to retrieve them i.e. Troubleshooting... Application Basics ... Profile Folder...Open Folder... which opened >>> C:\Users\AppData\Roaming\Mozilla\Firefox\Profiles\42o9xo83.default-release . Sadly, I am not a Teckie and I do not have a clue what the next move is to get my bookmarks back.

Can you please help me to get my bookmarks back. Thank you MM

PS... (I have deleted my username for security)

I am getting "Secure Connection Failed", Ive seen literally hundereds of same error also exist here. Like most of default solution (which is below) did not work for me. My laptops time is correct, And I highly doubt reddit and most of internet has issue with its security certificates. And other browser works just fine. So What is my solution other than immigrating to new browser?

Hey y'all, I just closed Firefox and tried to open in up again a few minutes later. The icon in my taskbar threw an error saying it couldn't find the executable. I typed Firefox into the run dialog and FF came up but has no icons on the home screen, zeroed out my bookmarks bar below the URL field and deleted all my bookmarks (100s).

I went into the User/../../Mozilla folder system and found a folder called bookmarksBackup or something similar. It was completely empty.

Any chance these were saved somewhere else as well?

Thanks

I have been working for Data Annotation for nearly a month and never got this error before. I need this money for rent! I'm trying really hard not to freak out here but today is the deadline for rent and the only way I'll get that money is to log on to this website so I need help and I need it now.

Hello, Since a couple of weeks I'm facing a strange issue on my Firefox installed on my desktop (arch linux) where the suggestions window that appears when clicking the URL address bar, is shifted upwards and covers the address bar itself and the majority of the bookmarks. Has anyone experienced a similar issue and is able to point me towards some troubleshooting steps? Thanks!

Firefox recently 'crashed' on my desktop PC. It asked me to restart in safe mode or restore to the original state. I chose to restore. This meant that I had to re-add all of my add-ons and log back into my favourite sites as my log-in details had disappeared. I got everything back to normal eventually, except for one very important site. I am now no longer able to log on to my bank website to review my accounts. I get an error message on the site saying " Log on error. You need to enable cookies in your browser to logon to Internet Banking." I have never had this problem before. I am able to log on successfully on my tablet, and also via a different browser on my desktop PC. I'm not a tech expert so this is very frustrating. I've tried clearing cookies/cache/data in the settings but no success. I really need to access my bank accounts on my desktop as I find this easier. Hopefully you can help as I don't want to use a different browser.

Best regards Andrew Sambrooks

I tried redownloading Firefox after I saw that i was unable to download any extenstions/add-ons. Anytime i try to download something from the firefox browser, the download fails or gets cancelled. I never changed any settings, how can i fix this?bold text

Ive tried reinstalling firefox because i am not able to download anything with this browser. I thought freshly installing firefox would fix the issue and allow me to download but it didnt. I also am tried to download an addon/extension, and that automatically fails to download. How can i fix this?

EVERY [removed] DAY firefox looses my tabs, historys, extensions/addons, prefferences and settings.... EVERY [removed] DAY!!! why am i wasting hours each day trying to recover basic [removed] ur piece of shit web browser clearly cant retain. even [removed] BING would be better at this point. ive tried everything at this point even down to tab managers but again without the webrowser holding extension info this too is [removed] useless. whats more annoying is it has clearly been an issue for over 8 years with a 10sec google search.... SORT YOUR [removed] OUT!!!!!!! yes im on windows, yes im up to date, yes ive tried resetting ur web browser, yes i have a [removed] folder with "old firefox data" on my descktop i cant use, yes ur web browser is a piece of [removed], yes i will be uninstalling this [removed] shortly. sadly i still remember the day firefox was king...... o how the mighty have fallen..

Have been unable to view readers comments for a number of weeks and can figure out how to fix. it is not all the time, like last night were available but not this morning. All other browsers there is no issue including DuckDuckGo. Am using Ublock Origin, but have been using for years with no issue, even when turn off result the same.
