When I open a .jpg file, the Firefox web browser window width is too big. I want to change the default window width. Which item in about:config controls this setting and what value should I enter to have a default window width of approximately half the screen size?

Hi,

In the older Firefox version (92), I could instantly open JNPL files by selecting "Open with Default Use JAVA (TM)". However, in the latest Firefox version 127, while the option is still available, it doesn't instantly open JNPL files. Every time I have to click to open the JNPL file.

I've been using Firefox for years on Windows 10 and earlier, and I just got a new Windows 11 laptop. On the new machine my bookmarks sidebar doesn't persist. I launch Firefox and open it, but when I exit Firefox and launch it again the sidebar is gone. I have to re-open it every time. This is not the behavior I experience on my other machines. Is there a setting in about:config that I need to change?

I have checked the "Always ask you where to save files" box in settings, but it is being ignored. I tried clearing the the "Save Files to" field, but that doesn't empty.

Firefox 129.0.1 (64-bit) running under Win 10 Pro on a Dell XPS 8910.

Please advise.

I was wondering if it would be possible to make an extension or something that can change about:config values and provide an easy accessible menu to change specific settings that I need regularly.

For example, recently I am quite often setting network.http.redirection-limit to 0 because website keep redirecting me to login pages and that often helps preventing it. But having that set permanently is really annoying, so I have to visit about:config twice each time. Now if I could pin that setting in an easily accessible menu somewhere, that would be very neat.

When searching, I found that extensions could modify some browser settings but that seems to not include arbitrary about:config values.

Any tips and thoughts would be appreciated.

oh, before I forget, it'd be very helpful if the entire 3 paragraphs previously entered were saved when the Share Data link is pressed.....

FF 129.0.1, on 64-bit Windows 10

while troubleshooting why a child page (which has links, text boxes) acts like it is displaying an image, not a working web page, I opened Settings, and at the top of the first page found the image (via Screenshot) attached -- "Your browser is being managed by your organization". thing is, this is a personal laptop which has never been part of an organization. is it referring to FF, since the program was in 'Troubleshoot Mode' at the time?

Regarding the parent page/child page issue, suggestions are welcome (solutions even more so ;-) )

TIA, Rrtid54

Hello, Firefox is my browser of choice for privacy and accessibility reasons. However, the speech recognition software I have been provided (Dragon professional 16) requires an extension to be installed that Firefox does not allow.

I was given the following information by Nuance, the company who manufacture the software: "The Dragon Professional web extension for Firefox is not anymore supported in Dragon 16 as Mozilla has blocked this web extension quoting a violation of their toughened security guidelines and requirements for such browser extensions on 10.06.2023 with the release of Firefox v105.

The reinstallation of the respective XPI file does not resolve the issue, especially because there is - and likely will be for the time being - no new adaptation of the web extension available.

However, our web extension should work fine if you decide to opt out of blocking extensions that have been listed as potentially dangerous by Mozilla. On your own risk you can prevent Firefox from carrying out the blocklist by changing the appropriate setting in the browser's configuration ("about:config") but Nuance does not recommend this. Further information is available from Mozilla."

If anyone can help with this, as I need the software for accessibility reasons and I don't want to be forced onto another browser because of it.

I can click on location (currently Kingfisher, OK) and then in the menu my location comes up (Mansfield, MO)but when I open a new tab Kingfisher is still there. I have done this many times, still reverts to Kingfisher

How do I either stop videos from autoplaying or auto repeating? Either one would be a blessing but I've searched and cannot find an effective way to do it. Blocking in Firefox is not effective. Mostly it seems in facebook, but I believe it repeats all the time on all sites.

I've read through lots of instructions, and tried to list a site as an exception to the ad blocker, but it doesn't seem to work. The site that I want to be able to contact me is Rakuten.com. Please help. This seems so complicated.

downloading only produces " .part " files in my downloads directory. I had previously attempted a large file download but error message said it was not completed. Now cannot download anything

I tried changing my color contrast settings to "never" BUT STILL, this thing still has a solid color. i'm making a web page, i tried using neocities, strawpages rn and also i visited other sites and they keep getting the same solid color problem, im tired. you can see how when im editing my site it has a anime girl background but then when i visit my page itself i dont see anything, i know eveyone can see it but im the creator and it really bothers me.

In the Privacy & Security pane we have the following configuration

Clear history when Firefox closes with all items selected except for Site Settings. Delete cookies and site data when Firefox is closed with some exceptions in Manage Exceptions.

But after quitting and re-launching Firefox there frequently entries for random websites shown in the "Manage Data..." pane.

This seems to related to having Facebook Container and Firefox Multi-Account Containers extensions installed. It does not seem to happen when they are not present. Interestingly. we had been using a a very similar Firefox configuration on a legacy Intel macOS system without this issue. We began seeing it while setting-up a fresh installation of Firefox on a new Apple Silicon system with macOS Ventura. The issue was reproduced in a new profile. It continues to the present day with up the current version of Firefox 129.01 on macOS 14.6.1 I feel like this is probably a bug but I don't have the necessary skill to make an effective bug report.

I want you to let the control key free for me to use as I have always done for other programs. Why did you took direct control of that key? It always opens a new window I do not need. I use control key plus c key to open another program and now I cannot open it with its own keys combination: control-c-c. Please, tell me how to disable it and stop it opening a new Firefox window. Thank you very much in advance for you kind help.

How do I change the order links open in new tabs? So far I've only found two orders they open in: X, X, O, X Using the above as an example, O will serve as the active tab that multiple links are being opened from. The only two orders I have found tabs will open on desktop are as follows: X, X, O, X, 1, 2, 3, 4 X, X, O, 1, 2, 3, 4, X But the order I am looking to achieve is the same order that the mobile app opens links in which is as follows: X, X, O, 4, 3, 2, 1, X I have already tried all combinations of the advanced settings "browser.tabs.insertAfterCurrent" and "browser.tabs.insertRelatedAfterCurrent" but still have not been able to achieve the desired order.
