Hello, as of recently Firefox got the new tool to highlight text in the native PDF viewer, and I really enjoyed using it. As of today, I had not updated or changed versions, but I suddenly lost access to the highlight tool option. Refreshing the page didn't work, downloading a new PDF and opening it didn't work, restarting Firefox didn't work, and I haven't seen anybody else have this issue.

Firefox Version> Firefox Developer Edition 125.0 Beta 8 (20240403091602) OS> Windows 11

I don't know if this is just an issue due to it being in beta, or it being on beta 7 but not 8, but either way any solution is appreciated!

I can no longer log into my social security account using Firefox, but the login does work on edge. When I try login on Firefox, I get the following error message:

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

The initial web site is https://www.ssa.gov/. From there I hit "Sign in", and get to https://secure.ssa.gov/RIL/SiView.action using Edge, but get just the error message using Firefox.

There is another route, which is through https://www.ssa.gov/myaccount/. Hitting either account or sign in on that page will work on Edge, but gives the same error message on Firefox.

It's ough to get all the photos and all the previous Facebook accounts back The next thing I want to ask is that I want to remove all the hacks, please help me to get out

For years, I have used print to pdf in Firefox to generate pdf files of long web pages. It always worked. But lately, I noticed that huge numbers of blank pages are inserted in the pdf file, seemingly at random. I looked at the HTML source, and could not see anything that obviously triggers the blank pages. For example, a web page that ought to print to about 35 pages generates a file of more than 600 pages, with most of them blank.

I can use Microsoft Edge as an alternative, but pdf files from that browser strip out all the color, and are nevertheless super huge, about ten times larger than the ones from Firefox. E.g. the file mentioned above, about 35 pages, would be about 1.3 MB from firefox, and 12 MB from Edge. So getting the file from Firefox would be nice.

Is there a reason why print to pdf is behaving in this strange way, and anything I can do about it?

Hi, Mozilla team I hope that you have a great day, straight to the point, my UI sometimes crashes or some components glitch or don't even work as it has to This is a video below slowed(I couldn't upload the video).

Hi Mozilla Suport teams, i am currently using the mozilla for the developer version and the app runs flawlessly, and i love it. But i have some suggestion for the developer at mozilla to make a tab that can group the tab into a fresh tab like the google chrome has, and since i open so many tab in this browser, i would absolutely love it where the feature of grouping tab is available for me, so i can group them in name and leave it there, rahter than open up more than 10+ tabs in a window. Thank you so much

Hello! Can you help me sort out a little problem? I am reaching out to seek assistance with a specific issue I am encountering in the Firefox browser.

In my previous browser, when opening new tabs, they were considered active even if I did not immediately switch to them. This behavior allowed me to open multiple tabs, for example, by using the mouse wheel to open several videos from the main YouTube page. Subsequently, when closing the main page, the videos would be available in the order they were opened, facilitating a seamless viewing experience.

Upon transitioning to Firefox, I have attempted to configure the browser to replicate this behavior using the Sidebery extension. However, even with the extension, new tabs are not recognized as active unless I explicitly switch to them, making it challenging to maintain the desired tab activation order.

I have explored various settings and experimented with the Sidebery extension but have not been successful in achieving the desired result. In contrast, the Yandex browser, with the "Switch to the previous active tab when closing a tab" option enabled, behaves in the manner I am accustomed to.

Could you please provide guidance on how I can configure Firefox to consider new tabs active immediately upon opening, regardless of whether I switch to them immediately?

I added pictures to make it clearer what I'm talking about.

Thank you for your time and assistance.

Hey folks, I use the firefox developer edition and I downloaded a zip file in it's private and when the download was complete I closed the window and open the download folder but the file was not there I haven't change the downloads folder location

Today when I close many tabs using control w firefox seems to randomly jump around when choosing which next tab to close

I wish to have firefox always close the adjacent tab to the tab I just closed

This should be the default behavior ... I do not see any setting for this ... is there an addon to do this ?

I am using the latest firefox on ubuntu

• • • UPDATE*** below answer for setting `browser.tabs.selectOwnerOnClose` has no impact on this

I have had this problem for a while. I am not sure what to do so that I can fix this. Whenever I open a pdf or any application that can be opened in the browsers shows me two options for firefox browser. I attached a picture that will make it obvious what the problem is.
