Is there any way (as in Thunderbird, via layouts.css.devPixelsperPx) to enlarge everything on a given monitor/display/colorDepth setting? Or an approach using userChrome.css that impacts everything, not just displayed text in the browser. Yes, this is a "tired old eyes" (excessive nanoseconds spent looking at bigger and bigger displays with higher and higher resolution) type question. My setup is multiple boot OS including Windows 11, Ubuntu, Manjaro, Arch. In each Firefox is the default browser, but Chrome and Edge seem to have more fine-grained controls for managing the chrome display than Mozilla. Using the latest 64-bit Firefox (100.02) if that's helpful.

Using Firefox version 102:

Open console tools and navigate to Network tab Right click on a POST request "Edit and Resend" is no longer an option? There is still the resend option Clicking resend allows you to edit the request, but unfortunately the "Content-Length" attribute is not automatically updated like it was with edit and resend, so all requests fail after being edited. This is because the Content-Length header indicates the size of the message body, in bytes, sent to the recipient. When you add or removes bytes in a JSON request for example, it doesn't get updated. The attribute can also not be manually set. How can I use version 102 to edit and resend requests the same way I used to?

Thank you.

Since the last update to Firefox I have not been able to print using the system dialog. Only the new Firefox print screen comes up. How can I return to system printing dialog?

Also the ability to set print quality in the Firefox print screen does not exist. I can do copies, black or color, duplex printing, etc but not set the print quality like draft, text, photo, etc.

I also have many forms I've setup for printing and I can't access these.

Thanks, Pat

I am having the identical problem as this person was.

https://support.mozilla.org/hsb/questions/1370443

I'm using Windows 11, Firefox 106.0.3. I have already selected "always ask." I do not see any way I can change the thing that says "Downloads." I see that there is a suggested fix, and I also see that an apparently knowledgeable person has advised against using that fix.

This is very basic browser functionality, and being unable to save to particular folders adversely affects my productivity. Is this issue being dealt with? What problems can I expect to occur in the future if I make the suggested fix?

Thanks in advance.

Up until today, PDF files would open automatically in Adobe where I could look at the file and print it. Today, Firefox will only allow the file to be downloaded. This causes me grief, an extra step. One of the main reasons I use Firefox is for this feature. Is there a way to change settings so that PDF files will always open in Adobe?

When I use firefox on my main display (1920x1080 144h 16:9) in full screen there is a noticeable white line in the bottom, not using full screen fixes it, but a pain in the ass to resize it all the time. I tried using the browser on my secondary smaller display (1920x1080 60h 16:9) and there is no white line. This seems to be a bug, how do i fix it?

Recently if I browse pages with maths forumulas they do not display coorectly, instead the underlying Tex or LateX code is shown.

I have several computers and I use Firefox on all of them, but curiously this problem does not happen on all of them, some show formulae correctly.

The image attached shows an example at Wikipedia - Lagrange point . The upper portion is Chrome and displays correctly, the lower portion is Firefox where the formyuals do not display correctly.

This is only started recently. Previously I had no issues with formulas displaying on any pf my computers, for many years.

CORS error in Firefox incognito mode only

Hi there, I am working on a site with Segment API and need to load their JS on my site for it to work. Whats happening is, I get the following error: "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://api.segment.io/v1/p. (Reason: CORS request did not succeed). Status code: (null)."

The weird part is, it happens only in Firefox incognito mode. It works on Chrome, Edge, Opera.

I am wondering if this is by design or if it is a bug.

Firefox version 98.0 (64-bit).

Hi!

I can't scroll with the mouse wheel in Firefox. It works fine in other browsers and programs.

If I switch to Safe Mode, the scrolling wheel works. But if I switch back to normal mode, the wheel does not work again.

I tried to switch off and switch on "Use autoscrolling" and "Use smooth scrolling" settings, but it didn't help.

Unfortunately, "Refresh Firefox…" and reinstalling browser completely did not help.

I am at a loss, please help.

I went into about:config and changed the following values in order to widen the scrollbar:

css. scrollbar-width was true changed to false idget.non-native-theme.scrollbar.size.override was 0 changed to 100 widget.non-native-theme.enabled was true changed to false

Changing these values didn't widen my scrollbar. Without getting into coding, is there another way to make the scrollbar wider? (I changed them all back to the original settings when they didn't work.)

Hello! Just installed Ubuntu 20.04.4 on my laptop and now find that I'm not able to watch some YouTube videos on Firefox 97. It seems mainly just live streams that I can't watch. When I go to one it shows "Your browser can't play this video...Learn more" in the video window. Clicking Learn More takes me to a page that doesn't explain what the problem is. Any idea what the fix might be? The same videos play just fine on other devices on my network. Any help would be greatly appreciated.

I'm running Win10. When in FF browser the taskbar, which I have set to appear at the bottom of my screen, does not appear. I normally use "auto hide taskbar" setting in windows, and tried to turn this off to see if the taskbar would again appear while using FF. It did not. So, the taskbar seems lost when in FF. This has happened before, appears it is an intermittent issue. My windows10 is fully up to date as is my FF browser.

Just lately I have been finding that, for a few websites, they are unusable because the screen looks extremely blurred. I have attached a screenshot. Compare this with what you see at ba.com.

I am wondering if this is caused by a new secure feature of FF which is incompatible with these few sites. Really, any suggestions would be welcome. Otherwise I have to use Edge..
