I'm unsure about this setting. I don't want a tab to reload when it's switched to.

It seems to indicate that something will be reloaded regardless of what I choose. I assume that's probably not the case.

Please confirm.

Good morning, Our company's firefox add-on(Saba Security Plugin) has stopped working, please let me know what happened.

When a new client (version 126) downloads the add-on, the following message is displayed: "The add-on downloaded from this site cannot be installed because it appears corrupt."

If you install an older version, it works without any problems, what is the reason?

I have already contacted you once at: product-help@firefox.com

And they told me to report at: https://support.mozilla.org/questions/new/desktop/form

Regards,

I want to change "browser.sessionstore.resume_session_once" preference to true. So I do it in about:config page and if I reaccess this page in another tab within the session, then my value is being kept.

However, when I restart Firefox (thru "Exit" in "File" menu), all previous pages get restored and that preference is "false" again in the config after a new browser start.

I also made a user.js file with the following content: // user_pref("browser.startup.couldRestoreSession.count", 0); user_pref("browser.sessionstore.resume_session_once",true);

Nothing helps.

Please let me know how I can modify the config file.

Thank you!

Dear supporter, our firefox is managed by our company, while download file, not sure why some file type could not setup default option, due to no check box "Do this automatically for files like this from now on", could you share how to fix ? Thanks a lot.

best regards/hing

I can edit my short cuts. One I have added the Name, and the URl, I also have the option to add a custom picture to the square icon for the shortcut. It seems obvious to want, as I do, to "drag and drop" a photo of my choice from my personal collection. For example, when there are multiple shortcuts for the email of each person in the family, their individual photo is a great identifier. As things are now it seems I can only add another URL. I tried to add the URL from a family members Facebook page but it would not accept the link. Can some techno whizzz out there not make "drag and drop" an option? It would be REALLY useful for us all to have the photo of our choice, either a family person where appropriate, or a pet or whatever, or a friend. Thanks. Drag and DRop seems such such a common process now I cant think it would be difficult. Well....I wouldn't know where to start of course, but thats why this is a Help forum! I look forward to you coming up with something! Thanks. Have a great day.

I'd like to use my NAS download application to handle magnet links. How can I do that with Firefox?

For mailto: links, you can specify web apps like GMail, same for e.g. IRC. However, for magnet: links, this is not possible, only local applications are supported. I even got an error message by the web application offering to configure this, saying the browser didn't support configuring this protocol.

Hi all, I need to solve a problem that is a bit annoying. I am on ubuntu 22.04 and using SNAP Firefox 127.0 (64-bit).

When I am prompted to select a file, for example to upload an image, the file picker is shown. However the thumbnails are so small(and right now I only see the image name) that I cannot see what's the content of the image. I managed to show a preview on the right of the single selected image by modifying an option in about:config. However it is still a pain to find the image I am searching for when I have a long list of images. Is there any way to enable zoom on the list of thumbnails so that I can preview the contents of the images? I don't understand why there is no option to customize the display of the file list. In the attached image I show how it looks right now.

Thank you

Hi,

Thanks for your help with this. When I search for something in FF and click on the MAPS button, it comes up with Apple Maps by default. I would like that button to open Google Maps by default. (Mainly because Apple Maps misses a lot of information and significantly hinders my searches. Invariably, opening Google maps gets me to my answer or information much quicker.

I have tried various help suggestions but simply have not been able to do this.

Please can you tell me if it's possible to do this and if so, how?

Thanks again.

Hi, I am experiencing an issue with desaturated icons in the toolbar and tabs of Firefox. I don't think any extesion may be causing this problem and i have already tried reinstalling and resetting Firefox, but this did not resolve the problem.

When scrolling through online pictures or even while typing this note, Firefox dropdowns get really annoying! It seems to be triggered by right-clicking the mouse on a link, misspelled word or button. It really is a PITA! How to stop?

My question is fairly simple. I have multiple microphones available to the system, shown in the first screenshot below. Most of these are physical microphone inputs, but I've also created a virtual device.

I am only able to use 3 of these, consistently the same 3 devices, in Firefox - shown in the 2nd screenshot. Interestingly, one of the devices that shows in Firefox (Teams Audio Device) I cannot find anyone else on my system. https://www.onlinemictest.com/ is a good site to allow selection of the audio device, but I get the same results across all sites that use audio - google meet being the big one.

I've gone through all settings menus and played with everything that I can find - resetting microphone permissions, clearing cookies.

I've accessed the same site (https://www.onlinemictest.com/) in Firefox Dev Edition, and I *can* select from my full range of microphones.

Interestingly, and just something I've noticed while submitting this issue, the debug info *does* include the mic devices missing from the menu!

Can anybody help me look into what's keeping my list of mics in this 'frozen' state, and stop me from having to use Chrome for work meetings?

Cheers!

If I press and hold the arrow key, the page scrolls for a few lines and then there is a delay of about a second before it actually starts scrolling. How do you remove this delay? For example, hjkl works exactly how I want it to in the vimium extension, but I'm also using home row modes, so I can't use it. I'm not talking about smooth scroll or something like that. I also tried Yet Another Smooth Scrolling WE and it's not what I was looking for. This delay also common to chromium.

Hi, I've noticed an inconsistency when clicking on Web-based protocol handlers in Firefox on Windows. Specifically, when I click on a mailto protocol, such as "mailto:email@example.com," it directly opens my default email application without any confirmation prompt. However, when I click on any other protocol handler, a confirmation pop-up appears, asking me to confirm which application to use. I have attached an example of what I mean.

Is there a way to configure Firefox to always show a confirmation pop-up for all protocol handlers, including mailto links? I prefer to have the option to choose the application each time rather than automatically using the default one.

I tried to change the font-size of address bar, tabs, sidebar and toolbar using the method given in The method given in: [https://support.mozilla.org/en-US/que.../1239467] gives no change at all of the font-size no matter the value I use. Any ideas? I'm using Windows 10 Firefox 127

Starting with Firefox version 120, you can set Firefox to automatically launch whenever you start or restart your Windows computer. https://support.mozilla.org/en-US/kb/open-firefox-automatically-when-you-start-computer

The browser shows opt-in prompt for the user to easily setup this behavior. However, I do not want to do this.

When I click "No thanks", the prompt goes away, but couple days later, it returns. I guess that an update resets the prompt status.

Is there a way to permanently disable this opt-in prompt without allowing Firefox to start automatically with the computer?
