Japanese characters usually do not render.

I can reproduce this issue by:

• going to the Wikipedia page for the katakana Unicode block.
• going to any YouTube comment with Japanese text.
• hovering over the screenshot of the YouTube comment so that the tooltip containing the name of the file is shown.

On YouTube the text renders only if 1.27916663885116563rem <= font-size <= 1.92083328962326036rem. Increasing `gfx.font_rendering.fontconfig.max_generic_substitutions` from 3 to 99 allows some punctuation to render and makes the text take up horizontal space. Further increase of the value to 999 causes the interpunct to render in the Wikipedia page.

Firefox Containers > Manage Containers > Remove [container]; message (modal, I think it's called?) pops up to say I have a tab open and do I want to proceed? I to up to the container icon upper-right, search for [container], click to open that page, then CTRL+W to close it. Then I try to Remove [container] again; fails. That container is still in the list, and still popping up a note that a tab is open in that container (no, I closed it).

I really like the Containers feature, AND it could use some improvement.

Unrelated, I'm open to help with proofreading; feel free to ask, or point me to a git where I could contribute. I'm not happy about the apparent erosion of privacy in Firefox, but it sure beats Google, Microsoft, Apple, etc.

I would appreciate whatever help or suggestions someone may provide to an irksome problem that only happens in my preferred browser, Firefox. I've attached an image below of a page from a local grocery store. Like most stores these days, it is possible to search within that store and its web site for specific items and prices, etc. It works in at least two other browsers I've tried but not in Firefox so a setting, I'm guessing, has been changed within Firefox in the last few months (because this problem did not occur before then).

As you see in the image, I've inserted an item to find its price; and nothing happens. Before, on Firefox, and now with other browsers, I would get a display of all relevant products, prices, quantities, sales and discounts, etc.

What Firefox setting do I need to change so this information will show up again?

I have Firefox version 137.0.2 on this system running Windows 10 Version 22H2 (OS Build 19045.5737).

Sorry for my ignorance; and thanks again for whatever help anyone can offer.

W 11 May, 2025 update really made my computer unable to go online in any way and I had to restore. But FFox updates to have made it impossible to communicate. My phone has trouble s too. So, how do we make stick telephone permissions for, say: G Voice page https://voice.google.com/u/0/calls now? Thank you

OS: Windows 10 Pro 64-bit with all the latest Windows updates installed; running Windows version 23H2. Firefox release I'm having problems with: 137.0.2.

Just upgraded to release/version 137.0.2. The first time I open Firefox each day it takes about 2 to 3 minutes for ANY website to load. Sometimes when a web page does eventually load none of the images display.

I have tried same websites using Google Chrome AND Microsoft Edge. Websites don't have problems loading using either of those 2 browsers unless I have Firefox open in another window. If they load slowly, as soon as I close Firefox, web page load quickly in Chrome or Msoft Edge.

Not a RAM problem because I typically have around 20% of my RAM being used.

Did not have any of these problems using Firefox version 137.0.1.

UPDATE: Thought maybe it was one of my add-on/extensions so I checked for updates. Four needed updating. Made the updates and website still no loading properly.

This problem started yesterday. The sound in YouTube with Firefox is extremely low. As far as I can tell, the problem doesn't exist elsewhere. Other browers are OK with YouTube and other websites that have sound are OK with Firefox.

I reinstalled Firefox and rebooted the computer - still has the problem.

I'm using Windows 11 24H2 (home) on my desktop.

As the first screen capture shows (sorry it's in spanish), my PDF documents tend to not print on the full page, but rather only on the top left corner of it, i've already fiddled with the scaling and fit to page, i have cleared the printer settings from mozilla, still the same, ive gone into the about:config menu and changed paper_height, paper_width, shrink_to_fit, and scaling nothing works. The document prints fine on Edge (screenshot 2), no problems with fit, and what's even crazier is that some PDF files work just fine (Screenshot 3). Honestly i have no clue what else to do.

So anytime about a month ago, everytime I boot up my PC then first thing I do is double click on Firefox to open it and that worked fine until a month ago, now when I do it youll see the circle spin for 1 second and spot but Firefox doent open, no matter how many times I click on it, the only way Ive gotten it to work is that I have to restart my pc and try again until it eventually DOES open when I click on it, I usually have to restart 3-5 times before itll open.

Im wondering why that is and how to fix it? I havent done anything new to my PC since then, no new Firefox addons, also if there was a problem with Firefox itself then restarting should never make it open yet it eventually works after a few restarts. soooo i cant be Firefox right? Ive also tried refreshing firefox as well as going to add and remove programs and uninstalled it then reinstalled it the issue still remains, any way to fix this?

I just downloaded firefox for the first time because Chrome disabled uBlocker. I have added uBlocker and 1Password as extensions, but neither of them are working on any webpage at all. I also can't pin extentions. I have restarted firefox and my computer several times. What do I do?

Today was the second time in two weeks I have lost every open tab in Firefox. Previous to this, this problem has not occurred in at least 5 years. What is going on? To utilize data from multiple sites takes a long time to relocate sites and this is becoming unacceptable. Firefox updates are better than this. Thank you for your help.

I recently updated my Mac OS to 15.4, and for whatever reason, ever since I did, Firefox stopped working. I can open it, but if I try to go to any web site it just has a dot bouncing back and forth like it looks like it's trying to go to the site, but then it times out. I have deleted and re-installed Firefox several times - the last one being version 137.0.2 for Mac, but it still won't open any site. I don't know what to do to get it working and Mac tech support had no ideas other than to contact Mozilla tech support, so here I am. Can you help me? This has never happened before and it makes no sense that it would not work. You can see by the enclosed screen shot that it opens, but fails to open any photos or go beyond that. The 'checking for updates' alert just keeps spinning and spinning. Rick Garside

I've used Google Maps in Firefox for years on a Surface PC. Over the past couple of weeks, I've found that Google Maps will select a route or routes, but they don't show up (highlighted in blue) on the page. What's happened? Is there a fix...?

Many thanks.

Best,

Stephen

When trying to do a search for a video in YouTube Studio, the search seems to freeze. Doing a similar search in Microsoft Edge works OK. This problem started happening several months ago. I've tried clearing the cache for YouTube pages.
