When clicking on a link to an .mp4 file, Firefox navigates to a builtin video player, streaming the remote video file. When Firefox is unable to stream or display a file (as is the case with .mkv or .txt for example), it is downloaded instead.

I simply want .mp4 files to be downloaded when I navigate to them. I tried setting `media.mp4.enabled` to `false`, and that worked, but it also disabled most embedded media players.

Hi,

I recently developed a Firefox browser extension using Manifest V3, it's to show coupons & offers on 1000s of online shopping website.

To function properly, the extension needs to have permission for 'Access your data for all websites' ( <all_urls> permission)

During installation, permission prompt does show up, but it doesn't ask permission for 'Access your data for all websites' but ask for other permission.

I have specified this permission in the permissions key in my manifest file. However, when I try to install the extension, It asks for other permission, but not <all_urls> permission: Screenshot at https://i.imgur.com/UiG5Dve.png

After installation, it start working properly only if user has manually granted permission from extension settings https://i.imgur.com/4QWOLOC.png Most users would not know this and may uninstall the extension if permission is not granted prior.

Please suggest the fix.

Here is how my Manifest V3 permission code look like https://i.imgur.com/JmMM3l2.png

I am using Firefox latest version and I have checked with/without any other extensions or add-ons that may be impacting the installation process.

I would greatly appreciate any help or guidance in resolving this issue. I believe the permission prompt is crucial for my extension to function properly and I would like to get it working as soon as possible.

Thank you for your time and assistance.

Best regards,

Krishna

Some text, and hyperlinks are yellow. Yellow text on a white background is impossible for me to read. Hyperlinks are normally blue. Can I change the text from yellow back to blue?

Hello,

I downloaded Firefox on a new computer. I logged in with my existing account and synced my data

This was successful. All of my bookmarks and extensions were downloaded properly.

I went into the customize menu to alter my toolbar. However, there were no icons for any of the extensions that I added, such as Bitwarden or Ublock Origin.

Due to this, I am not able to add these extension icons to my toolbar.

I verified that the extensions were all properly downloaded and that they work as they should.

I have already attempted to restart Firefox, uninstall and reinstall certain extensions, and to reinstall Firefox entirely. However, my extension icons do not show up still in the Customize menu

I am not trying to do anything in the Private Browser.

How can this issue be resolved?

Hello,

I need your help: how can I set navigation bar without any item (hide all items of this bar)? I need that this bar appears but empty. The reason is that I want to restrict options in Firefox (for all users) but let it be allowed open windows pop-up.

I got remove the menu button that is to the right of the whole (hamburger type), the forward and backward buttons that are to the left of the whole (which are the arrows to the right and to the left), the detention (which is the cross), etc. I did this with commands in userChrome.css file

But what I can't hide is the item where the url's are placed (search box). I just need to hide the search box. I wrote " #nav-bar { visibility: collapse !important ; } " in userChrome.css , and then all navigation bar is hidden but don't get windows of pop-up that I need them to appear.

The version of Firefox that I have is 108.0.1 (64 bits).

Could you help me, please? It's a little urgent. Thanks!!

Heyo,

I got a problem with saving extensions settings.

The error is: QuotaExceededError: storage.sync API call exceeded its quota limitations. How do I fix it?

I know that there has to be a way to edit the about:config to manually disable individual add-ons (addons) for certain sites. Some add-ons have this built into the extension itself but others (like Honey) are either off or on, but I cannot find any documentation on it.

I would still like to use the extension without having to remember to turn it off and on all the time for websites that I do not want it to spam suggestions at me. Thanks in advance.

Is this a new "feature?" The add-ons that I need to interact with frequently have vanished from my toolbar and can't be re-added; they don't appear as options in Customize.

I've DONE the "delete extensions.*" thing and the problem still exists. I even tried creating a new profile, but the icons didn't appear as I installed the extensions. It's as though Firefox has unilaterally decided to remove this feature and didn't warn users about it.

I still HAVE the add-ons and can access them from the add-ons list, but that's inconvenient since there are only a few that I really need to interact with; the rest can stay out of sight and quietly do their thing.

Is this a bug that crept into the latest update, or is it something that you're wishing on users? I've loved Firefox for years for its privacy focus, flexibility and customizability; please don't take an ease-of-use feature away from us.

Some sites offer separate links for viewing and downloading. (I'm specifically interested in PDF files, but I think this question is more general.) I'm not sure how this distinction is communicated to Firefox—I'm guessing in the MIME type? But regardless of the mechanism, Firefox does not seem to offer any obvious settings that distinguish between the two cases. Are there ways to distinguish in less obvious places, such as about:config?

As a specific example: currently on a certain site when I click "View" the PDF is displayed in Firefox, and when I click "Download" the PDF is both placed in my Downloads folder and displayed in Firefox. I would prefer that the "Download" link only cause the download, and not cause the display. How can I change this without breaking the "View" links?

I have tried all the methods the internet suggests. but nothing works. I still have the red dotted outlines on everything. Any thoughts?

These are the instructions Type about:config in the address bar and press Return. A warning page may appear. Click Accept the Risk and Continue to go to the about:config page. In the about:config page, search for the preference accessibility.force_disabled. Observe the Value column of the accessibility.force_disabled row.

       If it is set to 1 then do nothing.
       If it is set to 0, double-click on it to open an editing field, type 1, then click the blue check mark button or press the Enter key to complete the update.

Hi Guys Here is my problem: When I click on this button, the address will not open. This happens also when click on links to activate them to open an internet page. I do not know whether this is configured somewhere in my browser Mozilla or my computer protection McAfee program or eventually somewhere else. Have I blocked something in some program? Thank you for your help

I have a lot of extensions, and each time I get to a new device, I have to configure again which extensions are pinned to the overflow menu and which to hide. Is there a way to automate this? I'd also be fine writing a script if I knew the location this is saved at.

I need to capture & store "full page screenshots" using a Python program. This function is provided via the Web Developer Tool "Take a screenshot of the entire Page". Can I activate this tool from Python, perhaps with Selenium? Any other alternative would be OK too. Thanks.

Hi folks,

Since the last 109.0 update I've noticed a strange behavior with Firefox.

Sometimes after watching a video stream in full screen, my toolbar changes and moves all my customized icons / extensions etc. into this "more tools" drop down menu. I can reproduce this by repeatedly switching from full screen to the normal view

This is so annoying and frustrating.

Does anyone know how I can fix this?

Apple's built in spell checker on the Mac is unparalleled. Not only does it integrate with the native dictionary, it also automatically detects and switches languages as you type. Right-clicking on an unfamiliar word brings up the "look up" option which fins the word in the dictionary. It's furthermore smart enough to detect misspelled words which are correct words in another language. I don't know how apple achieved this, it's remarkable.

Anyway, Firefox displaces this functionality on the mac with their own dictionary, which although good, is not as good as the native spell checking and dictionary.

Is there a way to enable the native dictionary for Firefox on the Mac?

Is there a way for the new window animation in Firefox for Mac to be disabled?

Safari does not do this, but firefox has a... ~100ms animation for new windows that's extremely frustrating for those of us who do not use tabs (Apple's Exposé/Mission Control obsoletes them).

I haven't found a configuration in about:config, although I've been able to disable a few others.

Hi All. Love FF but there's one thing that's driving me crazy... the different color of the Library window (see screen grab). The main window is this nice dark "cool gray" color, but the library window is this greenish color.

Is there a way to change that? I've had the userChrome.css file installed and feel fairly comfortable making code edits.

Thanks in advance.

So this crazy new update has broken my Firefox in these ways:

1. All my bookmarks on my bookmarks bar have been deleted. 2. I can't drag any new links to the bookmarks bar 3. Overflow menu for apps is empty and will only let me drag Firefox defaults to it such as settings. Dragging apps to it is impossible. It "is" possible to pin items by using the Chrome puzzle piece..

Firefox: 109.0 OS: Windows 10 Pro

Using troubleshooting mode has no effect.
