I have discovered that I prefer closed captions with the letters in yellow rather than white. How can I make this change in Firefox on a computer with the Windows OS. Also, I would like bigger closed captions.

The new Mozilla Firefox (version 110.0) does not run after update on my system. After run it shows the window, but this window doesn't respond. The clean installation (of course with profile folder erase) doesn't fix the problem. I have tried both x64 and x86 versions.

The previous version installation (109.0.1) works fine.

There are some screenshots included. I use Windows 7 on Ryzen 7 2700X processor. Could you please advice, what can be done here?

Firefox won't stay my default browser. Every time I sign on after rebooting MS changes the default to I don't know what. It doesn't say what is the default. It wants edge I guess but I deleted the entire edge app and all its dlls. So how do I make the choice through the "set defaults" settings permanent?

My keyboard regularly locks up using Firefox. I tracked the problem down to having upwards of 40 Firefox processes running in Task Manager. Disabling them or restarting Firefox only works for a few hours before the problem recurs.

Several people here recommend disabling "Use recommended performance settings," which should give me the option of selecting the max number of processes to be running.

However, when I disable the recommended performance setting, the hardware acceleration option appears, but not the process number selection. I'm finding no way to set the max number of processes.

I'm hoping for a work-around to that, or a different solution.

Thanks.

BTW, I also notice excessive processes running when I use Chrome. I'm concerned why this is happening on both my browsers.

Visiting some web page firefox prompt for my primary password , i imagine to access the login data of the site, but in principle the site may ask for anyone of the saved login data (or not?), so in lack of a clear login page i wonder how to know which private data are requested by the page.

is there any way to see what data are accessed? This is especially relevant if i've already input the master password, in this case there is no evidence to the user that private data are requested and accessed.

If I have the inspector open from Web Developer tools, I can see the HTML elements presented under that tab. Is there anyway in Firefox's configuration settings that we can change the font-family for the HTML view under this Inspector area? (not globally for all of Firefox). If so, where or how can we make the adjustment?

I use ccleaner and somehow my setting got changed and it wiped out my history, except for the past 2 days.

I've got a backup places.sqlite from a couple weeks ago. Is there any way to add the two together?

Also, is there any way to import history without replacing the current bookmarks?

Whenever any website asks to access my location, and I allow it, Firefox tells that website that I am in a faraway place that I last visited over a year ago. What's worse, this place happens to be a very niche medical facility, which is upsetting as I don't expect to be revealing my medical history just by allowing access to my location.

I am not using a VPN or proxy or anything of that sort. If I look up my IP address in GeoIP2 or iplocation.net, it shows the correct city that I am actually in. How can I force Firefox to update my location (or at least, get it to uncache this old location)?

I'm using Firefox 109.0.1 on Ubuntu 22.04.1 LTS.

Hi there -

I just downloaded FireFox as my default browser on my new MacBook. Previously I was able to update the settings for how downloads behave. But I can't seem to find what I need now. Currently, when I download a file, FireFox ALSO opens it in a new tab...I don't want it to do that. I just want to download the file, but cannot find where to turn off its ability to also open the file in a new tab as I don't want it to do that.

Thank you for your help!

What is the Actions shortcut used for? I don't see anywhere that list possible actions or even identifies what the shortcut is used for but it's a default selection.

I have a sandbox iframe which is hosted by various websites. Lets assume that this iframe is loaded like this: <script src="https://example.com/wie.js"></script> I have already added 'allow-scripts allow-forms allow-modals allow-same-origin allow-popups allow-popups-to-escape-sandbox allow-storage-access-by-user-activation' at sandbox. I also use document.requestStorageAccess() from inside the iframe and I set event listeners for the storage like this:

window.addEventListener('storage', onStorageFunc, false);. From the iframe a popup window is presented when user clicks a specific button and the popup opens at lets say at this url "https://paypal.com". After user navigation on popup, paypal at the end of the flow redirects user to this url "https://example.com/success". At this point when user is navigated to /success I add some data to local storage which I expect to trigger the storage event listener and the onStorageFunc to run. This doesn't happen, while in other browsers it works as expected.

Since both popup and iframe are under the same url (https://example.com) and I have used requestStorageAccess, I would expect this to work normally. Can you please help me to find out what is going wrong here? In the past I had the same problem but it was fixed when I added 'requestStorageAccess' and 'allow-storage-access-by-user-activation'. Now I can see it happening again.

The native FF bookmarks search function only returns bookmarks that match the search term. How can I get it to also return folders that match? That is, if my bookmarks contain both a folder and a page whose name includes the word "climate", I need it to show me both of them when I search on "climate". Right now, that search returns only the page. Is there a setting or something that will make it return both?

The "Bookmark Search Plus 2" add-on does return both folders and pages. But it has another limitation: It doesn't have an "Edit Folder" or an "Edit Bookmark" function. So if I want to find a folder with search and then edit its name, I can't do it with either the add-on or the native bookmarks browser.

I am trying to add a secondary email and then make it primary, but the system wants me to verify my primary email, which I've long since deactivated. Can you please change [edited] @yahoo.com to [edited] @gmail.com

I would like NOT to lose my bookmarks, etc. Thank you! :)
