My Dashlane password manager extension wasn't working, so I deleted it and planned to reinstall it. When I tried to download this extension again, I got the following error message: "Installation aborted because the add-on appears to be corrupt."

I have the most recent update of Firefox 147.0.2 (64-bit). Please let me know how to fix this issue, as I heavily rely on this extension to sign in to most websites.

All of a sudden, my Yahoo Mail Contacts doesn't load. The following is the error message where my contacts should be listed. How do I fix this? Thank you

I have disabled and removed any and all VPN's from my main unit. I have reloaded Firefox and cleaned the registry. Still getting the message and am unable to display images. Any ideas?

Roblox was blocked on my device and I wanted to get it unblocked and play it on Infrexa with Firefox. I already followed steps mentioned on the official webpage: https://www.infrexa.com/now-gg-roblox-login-and-play-roblox-unblocked-on-your-browser so please don't advise similar troubleshooting methods.

Now I am able to play roblox but the problem is that when I play the Roblox through "Mozilla Firefox" it shows an error "Firefox is already running but is not responding" and then becomes unresponsive when pressing refresh button, the fan gets faster and device heats up with too much hanging. But when I open the Roblox through "Chrome" it comparatively works good and asks for login details and after redirection it allows me to play Roblox Unblocked without any issue. "Roblox unblocked" here simply means a technical sense, meaning “not crashing” or “free from software or network errors and or browser malfunction".

I have been using Firefox for a long time and my passwords and user ids are saved in the browser so I want to continue using "Firefox" as default browser but I am having the issue in playing roblox unblocked and other games through Firefox browser. I think the current issue that I have started facing is especially after a recent windows update.

I also tried many other gaming platforms like Official Roblox.com, Now.gg Roblox, easyfun.gg and web.cloudmoonapp.com but all of them faced same issues on Firefox while running ok on Chrome.

I am currently running Windows 11 (25H2 Licensed version). I want to play roblox unblocked on my device using Firefox (updated). My parents have already allowed me to play Roblox and I am playing it on my own device and internet connection. Please fix the browser issue and unblock Roblox for me. Please also check my browser version against Windows 11 compatibility if possible.

If you fix this issue for me, I will be grateful to you.

Windows 10 pro OS is persistently repeatedly blocking every attempt I make at Installing Firefox.

Basis: the exe. / installer, is potentially harmful to the PC.

My investigation: Is 4GB RAM sufficient to reasonably run my Lenovo ThinkPad Edge 420s(4401-7SG) PC? OS Windows Pro.

Firstly, because, It is annoying to manually have set browser.tabs.groups.smart.enabled and browser.tabs.groups.enabled to false every time when installing firefox.

Secondly, because this is not sufficient to restore the normal correct beaviour. Tabs cannot be detached despite browser.tabs.allowTabDetach being true.

FF 141.0 on FreeBSD, only extension is NoScript.

What needs to be done still so that tabs can be detached?

P.S.: Suggested long term solution: Introduce an option "Disable tab groups ENTIRELY, restore behaviour as it was before introduction of tab groups.".

I have two credit cards saved in Firefox 147.0.2. When a web site asks for my cc info, a yellow box opens identifying both cards. When I hover over one, the boxes are filled in in yellow. When I click on the card i wish to use, everything disappears and all of the boxes are blank and back to their original color.

I am on a MAC running Tahoe OS 26.2

What am I doing wrong?

Hi,

Since last week I am unable to properly use some websites that are failing due to CORS requests, but they were working before. Some examples are es.webuy.com or a local Jellyfin instance. After trying to enable/disable some settings that I thought could be related to the problem, like security levels, I ended up creating a new profile. In this new profile everything works, but as soon as I synchronize my Mozilla account, then these websites start failing again with CORS requests errors.

Any idea about what setting might it be the one causing problems? Or any idea about how can I debug/troubleshoot it myself?

Thanks!

I've lost my bookmarks after Firefox restarted after computer crash today. The bookmarks library is empty, and I could not find another profile. I could not find "Old Firefox Date" on my desktop.

I'm on a Macbook Air, Apple M2, Sequoia 15.3.1

I use Firefox (the current version) on a Dell Windows 11 Pro laptop. I have around 8800 bookmarks, and I've lost around half the tags on my bookmarks. (The bookmarks themselves are OK; I'm losing about half of the tabs.,) This has happened to me twice recently, and I'm restoring the bookmarks as I write these words.(after I'm finished, I'll save two copies of the HTML file for backups. Can anybody tell me why this is happpening, aaand How I can prevent it in the future?

Thanks.

On my steam deck, from time to time, the firefox's touchscreen support seems to switch modes.

The symptoms are:

- Instead of scrolling, one-finger touch-and-drag now zooms in and out (depending on direction)
- The touchscreen no longer lets me select or close tabs, or focus or click in-page widgets
- This mode-switch is restricted to the firefox window in which it happens
  - Moving the tab to a new window results in the new window working fine
  - Other existing windows are unaffected (although they may later experience a touch mode switch  event)

I have yet to determine what triggers this switch, nor can I figure out how to undo it.

I need to know how to make subtitles readable again. I want bright white on dark back ground. This constant dim gray on light back ground is terrible. I am elderly, deaf in one ear and wear a hearing aid. I need the subtitles to be readable.

Please tell me how to fix them if it is something I can change. Or is it something the channel owner is doing? That same question applies to the YT bingo card video rectangles. Sometimes they are giant and in a single row I like the 3 wide display, like a bingo card.

Lastly, why do the video choices display on the right side of the screen? That makes the info below them unreadable. They used to be on the left side so hovering over the text is readable. Who is charge of fixing that?

I have lost all bookmarks on a new laptop. Recently added C Cleaner and did a scan. That may have caused the problem. But, now I cannot recover the bookmarks, nor can I save new bookmarks. The version of Firefox on my android phone has the bookmarks. I can see them. But, I do not see a way to sync the devices and import the data to my laptop.

Please advise.

I have lost my passwords on my desktop. I still have them on my mobile. I am currently logged on to Mozilla on my Desktop. If I log on to Mozilla on my mobile and select "Synch" how can II ensure that the mobile passwords replenish those on the Desktop and not vice-versa?

Hi,

I was super pumped about profiles but it seems it has gone terribly wrong for me.

I created a two profiles on one computer and would like to reuse them on another. Apparently this is impossible, which is really too bad, please change that! Why would I want to redo everything on every computer that I work with? And it deleted bookmarks on other computers synched to my account, why?

And I deleted every profile on one of my computers, in the hopes to "start fresh" since I had lost all my work, and now Firefox refuses to open. It indicates "Your Firefox profile cannot be loaded. It may be missing or inaccessible".

So now I need to re-install the whole app. Just... Why?

Thanks!
