Tried four times in a row. Had the problem In 142.01. Updated to 143.01. No help.

First image is after the update attempt. I intentionally chose not to update 3 of them

Second image after relaunch.

I recently wiped & reloaded my computer. Multi-Account containers re-installed successfully & I see all my containers. The issue is with sign-in to Reddit.com website. If I try to login using a container, I get invalid username or password error. If I login without using a container, it's fine. I am copy/pasting my account info. I tried different containers; same issue. Tried creating a new container; same issue. Try again without using a container; login to Reddit is successful.

Hey!

Anyone has any ideas why the extensions does not work properly anymore? Or is in similar situation?

My browser has been updated, as well mentioned extensions (its only 4 of them really). They worked fine for years and now suddenly - when I click on them - there is no response! I refreshed and re-installed the browser as well. Restarting does not help either.

The add-on, Enhancer for YouTube, appears to be the cause of a very annoying bit of behavior. My YouTube tabs seem to be all numbered. I hate this. Why make a bookmark, I have to manually remove this number before I can auto sort my bookmarks directory alphabetically.

Worse, there is no part of the description that identifies this bad behavior as being involved with Enhancer for YouTube. I had to go to AI for help figuring out how to get rid of this exceedingly annoying behavior that showed up whenever I used tabs with YouTube videos. I can't imagine anything that this add-on could be adding to my experience that is more convenient than this particular behavior is annoying.

Changes to the appearance of tabs should not be performed invisibly and without settings that I can disable. Because of this, I can only get rid of his horrible behavior by disabling the entire add in. Mozilla put a stamp of approval on this particular add-in. So the dirt is on your face, too.

Hey folks, just wondering when the Windscribe add‑on will be moved to the MV3 framework. Other browsers already have it at v4.x and I’d love to see Firefox catch up so we can use the new privacy features. Is there an ETA on the review/approval process? TIA

Hi everyone,

I recently built a small Firefox extension for my website https://calcolo-stpendionetto.it https://calcolo-stpendionetto.it , which helps users calculate their net salary in Italy using updated IRPEF and INPS rates.

However, when I try to upload the extension to addons.mozilla.org addons.mozilla.org (AMO), I keep getting this error message: Signing is not possible due to an error with the manifest file

{

 "manifest_version": 2,
 "name": "Calcolo Stipendio Netto",
 "version": "1.0",
 "description": "Calculate your Italian net salary (IRPEF, INPS, regional tax) quickly.",
 "icons": {
   "48": "icons/icon48.png",
   "128": "icons/icon128.png"
 },
 "browser_action": {
   "default_popup": "popup.html"
 },
 "permissions": ["activeTab"]

} I also tried switching to manifest_version 3, but then Firefox gave a warning that some properties like browser_action are deprecated or not recognized.

Has anyone experienced the same issue when uploading finance or calculator-related extensions? Is there a new manifest format or signing rule I might be missing for Firefox extensions?

Any help or examples from working extensions would be greatly appreciated. Marien Klin

After having upgraded my W11 system to 25H2, I cannot install any extension. Installation terminates with "... something may be broken". I'm using FF 144.0,2. FF is used in more than one account alternatively.

On a second system, with less security measures, I have no problems.

Hello everyone,

Is there any software that allows software developers to see what the CSS they are creating is doing in real time ?

Because I can't imagine they're doing it blindly. I see some CSS files that have hundreds, possibly thousands, of lines.

If there is software that helps them see immediately what their CSS is doing, can it be used to create extensions (add-ons) for Firefox ?

Thank you for your attention.

In my new PC on Windows 11, I decided to install the Mozilla Firefox from the "Microsoft Store". However, unfortunately, I realized that some Add-ons (extensions) where missing from the Firefox's "Gallery of Extensions". Among them, the well known and valuable extension '"Enhancer for YouTube", which I have installed on every browser that I use. So, if I don't find a solutions for this issue, I am about uninstall the Firefox and reinstall it from Mozilla's Website..

I downloaded an extension and can't do anything with it. There is no way for me to open it, all I can do is open up my extensions to see it then change permissions or delete it. It won't appear on my toolbar with other extensions. I've seen others ask this question and the solutions dont apply to me. People are being told to either right click and click pin to toolbar or to click the gear icon next to the extension and then pin to toolbar as well. I have no gear icon next to extensions and right clicking an extension treats it like a link. There is a gear at the top that when I click it I can click "manage extension shortcuts" only for it to then pretend none of my extensions have shortcuts even though 2 of them are right there in my toolbar. The 3rd 1 mozilla seem to not want me to have on my toolbar.

I may have asked this before, When I launch Firefox, it opens the tab to the right of the active tab in the previous session. When I close a tab, it opens the tab to the right.

Am I wrong, or is that precisely the opposite of what you would expect or want?

Can someone please explain the logic of this? Is there anything that can be done about it?

I have this addon Select After Closing Current. Can I get some advice to set it up to work?

Also, why are there two product pages for it? link text

Some recent update has changed the way extensions function in Firefox. I used to be able to pin my extensions on the toolbar between the account icon and the extension icon on the toolbar. This is REQUIRED for certain extensions to function properly. One example is uBlock; when visiting a site it actively updates the icon letting you know its working and blocking unwanted items. Same with Facebook Container. Password managers such as 1Password also have stopped working for me unless they are pinned to the toolbar. You use to be able to click the extension icon and then see the list of extensions in a window. Now when you click the extension icon it opens to the Recommendations tab of Add-on Manager. You then navigate to extensions and see you enabled extensions but there is no option to pin, only manage/remove/report. I was able to fix this behavior once by completely uninstalling Firefox and then removing the left over folders on the C: drive. Once I reinstalled and went through the initial process of adding the extension, it also asked me if I wanted to pin to the toolbar. To which I said yes and got things working again. After clearing my browser history and cookies, then turning that feature off, it also blew away my pinned extensions. Even after removing the extension and re-adding, I do not get the prompt to pin like I mentioned above. So its seems I may have to go back and uninstall/delete folders/reinstall to get this working again. I see several similar posts so this appears to be either a bug or a very poor design choice on the part of Mozilla.

How do I fix this? I'm not able to use any of my extensions now and really don't want to have to randomly uninstall/reinstall every time this issue happens.

Hello,

I am encountering an interface display issue while using the AdGuard ad blocker extension in the Firefox browser on Windows. When I try to open the "Filtering Log" feature within the extension, the pop-up window appears completely blank and fails to display any log content.

Steps to Reproduce the Issue:

1. 1 Install and enable the AdGuard extension from the official add-on store.
2. 2 Browse any website.
3. 3 Click the AdGuard icon in the Firefox toolbar.
4. 4 Click the "Filtering Log" button (the icon that looks like a list or clipboard).
5. 5 Expected Result: The filtering log window should open normally, displaying a list of blocked and allowed requests.
6. 6 Actual Result: A new window pops up. The title bar of this window displays "Mozilla Firefox," but the content inside the window is completely blank (pure white, without any text or error messages).

Additional Information:

• Firefox Version: 142.0.1 (64 bit)
• AdGuard Extension Version: 5.1.139 (TSWebExtension v3.1.0-alpha.4 TSUrlFilter v3.3.3 Scriptlets v2.1.6 ExtendedCss v2.1.1)
• Operating System: Windows 10 22H2

Other Installed Extensions:

• Immersive Translate - Translate Website & PDF | by Immersive Translate | Version 1.20.8 | https://addons.mozilla.org/en-US/firefox/addon/immersive-translate/;
• Tampermonkey | by Jan Biniok | Version 5.3.3 | https://addons.mozilla.org/en-US/firefox/addon/tampermonkey/;
• Dark Reader | by Dark Reader Ltd | Version 4.9.110 | https://addons.mozilla.org/en-US/firefox/addon/darkreader/

Troubleshooting Steps I Have Already Attempted:

• Restarted Firefox.
• Disabled and re-enabled the AdGuard extension.
• Reinstalled the AdGuard extension.
• Tried running Firefox in Safe Mode (with all extensions disabled). The issue persists, suggesting it may not be a conflict with other extensions.

This issue prevents me from using AdGuard's core debugging functionality. Thank you for your assistance.

I would like to eliminate the websites which are done by an AI in my brownser. Especially those were no redactor is mentionned. Is it possible ?

Thanks

After many attempt, I cannot complete to add-on of the IBM Security Rapport , this is important and need assistance. I cannot locate in the add-ons or extensions using Firefox. Thank You

Hello, I have been using Firefox for more than 20 years, but I am now considering stopping. The reason is the new Firefox Translate extension. It constantly shows pop-ups, and there is no option to disable it. This is extremely annoying. If an option to disable this feature is not added, I will say goodbye to Firefox, because this extension works very poorly. It should only appear when needed—showing up all the time makes no sense.
