I am trying to print shipping labels from Amazon and a third-party web app running Firefox 103.0 64-bit.

Text prints just fine but images (barcodes, etc) that need to be scaled down do not do so causing them to be truncated on the page.

I have cleared print settings and tried two different printers to no avail. The documents/images print correctly from Chrome. I have tried using the system dialog to print but this also does not correct the issue.

Any help is greatly appreciated as I currently cannot use Firefox for the essential daily task of printing packing slip / mailing labels.

After updating to Firefox 103, everything in the browser including web pages, are way too big. Oversized. What the heck happened? Why do they do this? On the tool bar with the address field, on the right, I have a zoom icon, etc., and they're all much bigger!

I could adjust zoom, but this is not right. It's all messed up!

Yes I went into Customize Tool bar - Density - and it was already set to "compact - not supported"

I went into about: config - browser.display.os-zoom-behavior - changed to zero. Nothing happened.

I went into the windows settings - display - set to 125% which it always was. Changing to 100% didn't do anything. Went into display - Make display bigger - and it's 160, where I always had it.

Not happening in Chrome or Windows. So it's Firefox.

Currently @ Ver. 102.0.1 Problem remains. Since the update to 102.0 my Win10 PC has problems with the page update. When the scroll slider gets near the bottom the page, new images begin to load. This reload results in 3-15+ newly loaded Fb posts scrolling past so fast as to be invisible. I have to keep my cursor on the scroll slider and, when the loading begins, start scrolling up if I want to have any chance to easily find the last post I was reading. I have seen this behavior, grossly exaggerated, when I was viewing a video. The reload caused the viewing to pause and upwards of 15 newly loaded posts scrolled past in this rapid manner. My work requires that I am able to view pages of Facebook posts and this is now massively time-consuming and intolerable. I may have to change browsers in spite of my reluctance to do so.

Random videos will not load following 100.0.2 install.

These symptoms started @ May 21. (See attached file "Recently installed")

This problem is 100% reproducible at: https://www.reddit.com/r/CatastrophicFailure/

Lenovo Thinkpad x140e Windows 7 (all updates installed) Mozilla 100.2.8174

Scrolling down the Reddit page, videos will auto-play when exposed, and stop when scrolled past.

A video not loading/playing will occur on different posts/videos, but will ALWAYS occur. Once this occurs some previously exposed / played videos, when scrolling up, will play when exposed again, and some will not.

This will also randomly occur on Youtube (also observed on Twitter a few times) when multiple tabs are open. Sometimes closing other open tabs corrects the problem. Other times closing Firefox and relaunching is required and is 100% effective.

I have additional diag data / Inspector log files and page source if needed.

Thank you in advance for your help and consideration. - LudditePro

I have Firefox 100.0.1 on my Mac desktop, and Firefox 100.0 on my MacBook Pro laptop. I can no longer access my Microsoft OneDrive account via the web on my desktop, but I still can do so on my laptop. I have gone through your posted troubleshooting steps for Firefox on my desktop, to no avail. How do I get my desktop back to version 100.0 so it will work again? I can access my OneDrive account via the web on my desktop when I use the Safari browser, so the issue is definitely with Firefox version 100.0.1, and not with my desktop.

Firefox 102esr has almost every menu, popup and screen in dark mode - which I find extremely difficult to read, given I'm antique.

I've tried all the modes like light, system etc nothing seems to fix it.

Am I going to need a stack of css code to fix it - code for each and everything I want to set back to light, or is there a setting to achieve this?

Like in

https://support.mozilla.org/en-US/questions/1224759

my twitch tab stutters when i change from a different tab to the twitch tab. I don't have it everytime, it's really inconsistent. It appears that my video moves forward some seconds. Suggestions like in the link didn't helped for me.

I tried: - set media.suspend-bkgnd-video.enabled to false and restart -> didn't solve the issue -set media.suspend-bkgnd-video.enabled back to true and restart -> didn't solve the issue -set media.suspend-bkgnd-video.enabled to false set network.http.throttle.version to 1, restart,

 set media.suspend-bkgnd-video.enabled to true again and restart -> nope

- set network.http.throttle.version to 0 and restart -> nope.

I'm really helpful for any ideas. Thanks in advance!

After the most recent update, v.103, any image-based PDF that I print out is extremely oversized despite appearing correctly in the print preview window. I have tested other browsers and did not have this issue. I have also reset my Firefox print preferences and my printers/drivers to ensure it's not that either. Does anyone know what could be causing this, besides an issue with the new update?
