Installation aborted because the add-on appears to be corrupt. OmegaSwitch

Hello, I encountered an error when trying to install the extension. I've never encountered anything like this before

A new version of the "List All Tabs" appeared on my toolbar today, shown on the left and hovered over in the attached screenshot (ignore the Malwarebytes extension icon). The old icon for this button was a chevron with approximately the same functionality. I was able to remove the old icon, but I'm unable to find a way to remove this one. Here is what I've tried so far:

• Like the old one, the Customize Toolbar feature is unable to remove it since it is grayed out.
• For a while, I was able to remove the old icon by going to about:config and setting browser.tabs.tabmanager.enabled to false. This solution does not work for the current and some recent versions of the button.
• I attempted to create a userChrome.css file (following all the steps according to this this website) and added the following string: #alltabs-button { display: none !important; }

None of these attempted fixes have removed the button following a browser restart. Is there a way to remove it? I have no need of a button that shows me what tabs I have open when I can simply look at my toolbar.

Is it possible to install Firefox (or at least the profiles) onto an external SSD (i.e., not the C: drive)? If so, how?

Note: this is not about migration/backup/recovery of profiles. Nor is it about where files are downloaded by default.

Windows 11 is consuming nearly all of the C: drive. I badly need to get Firefox (and later Thunderbird) onto my E: drive. I further note that the installer gives no options whatsoever as to the destination drive.

Most of the help I've found on the web is clearly outdated.

Thanks. jt

Hello, I am currently using Firefox Beta and I would like to switch to the regular Firefox Release without losing any of my data (browsing history, bookmarks, passwords, add-ons, and settings). I would appreciate guidance on the safest recommended method. Specifically:

Is it safe to install the Release version over Firefox Beta, or could this cause data loss or profile conflicts?

What is the best way to create a full backup of my Firefox profile beforehand?

Should I expect any issues with add-ons after moving from Beta to Release?

Do you recommend enabling Firefox Sync as an additional safeguard, or is a profile backup enough?

In case something goes wrong, what are the recommended recovery steps?

My setup:

Operating System: [windows 10 ]

Thank you for your assistance.

firefox setup 127.0.2.exe offline installer fails with message about "extraction failed" and popup "file is corrupt".

Windows explorer shows file properties and a signature for mozilla.

Is there a way to manually unpack the .exe? Someplace that issues are logged with more data (which file is corrupt?) There is a progress bar that flashes by part way, then a popup window with the file corrupt message.

(Trying to update to hopefully get rid of some crashes.)

Is there a hash for that .exe I could check?

Hello, I have problem with firefox. When I try download from facebook page files .docx, .xlsx (Microsoft Office) Firefox automatically download it as PDF and file is broken. I don't know how to repair this. Please help, it is very frustrating.

You guys keep hijacking my browser and stopping all my work on a near weekly basis. Shutting down my ability to work on projects and stopping my browser from functioning in the middle of use. I can't even pay bills without you guys interrupting my browser with your bullcrap.

This is unacceptable. I've gone through great lengths trying to stop you from hijacking my browser. I installed a policy generator and followed the instructions to put a policy in. I uninstalled Firefox's background updater tool. I disabled automatic updates in the settings to the best of my ability.

I've gone through everything I can think of trying to stop your forced updates. Its unethical what Mozilla is doing to its users. I even tried to lock policies with admin only authorizations but firefox couldn't read the file anymore when I did that. I did confirm today that the policy file was still working, when Firefox ignored it and shut down my browser till I restarted it. I confirmed that Firefox is blatently ignoring policies.

I just checked and Background Maintnence was installed again when I didn't want it. You're now installing software against my will too? What the hell is going on.

I'm not able to uninstall PWA apps created in Firefox 143.0.1 using Windows 11 usual uninstalling procedure. If i click "uninstall" in Windows Start Menu the app remains installed. PWA apps created with Firefox do not show on Windows 11 installed apps list so I cannot uninstall them. I haven't found any guide on the web on how to uninstall PWA created from Firefox. So, how can I effectively uninstall those PWA apps? Thank you in advance for your kind answer. Regards.

I just installed an update when prompted by Firefox. Now I can't log into Hotmail.

FF 129.0.2 x64. The update restarted FF. Everything else seems to work OK. But when I go to Hotmail.com, at first it displays my Hotmail inbox - which is odd; all other webpages requiring a login were logged out when I installed the update, requiring me to log in again - but then it switches to an error:

Something went wrong and we can't sign you in right now. Please try again later.

The Microsoft account login server has detected too many repeated authentication attempts. Please wait a moment and try again.

The same Hotmail account is still logged in and functioning on Chrome. This is why I think it's a FF-specific problem.

This refurbished laptop was purchased from Best Buy in August 2022 with a Windows 10 OS. When a free upgrade was offered by Microsoft to Windows 11, it was accepted. Why are there no drivers with a version 11 prefix?

I'm curious about integrating Internet Download Manager with Firefox. Can you provide a quick guide or steps on how to achieve this seamlessly? Your assistance would be highly valuable. its important to me because i run a small online bussiness of Office Cleaning Solutions and i upload and download vedios from my site. but IDM is not integrated . Please solve my this quary.

Once again, when I updated Firefox, it changed a LOT of my settings, including displaying the toolbar and open tabs bar.

When this happened last - months ago - it seems Mozilla realized this had happened to a lot of users, and managed to restore us to all the information that had been "lost".

I hope you can do that again, and can find a way to not put at least ME, and I'd bet a lot of other users, through the OMG!!! What do I do NOW?! panic.

Happy Holidays.
