Firefox Community Forum

I am a Cacti developer and we are considering switching from FontAwesome Web Fonts to Tabler Web Fonts. However, on Firefox for Windows only, we are having a major slowdown when using the Tabler SVG based webfonts. The page load is first stalled by Firefox apparently loading all the Web Fonts, which would appear normal with any browser (though exceedingly slow on Firefox for some reason).

However, once the page is loaded, when going off tab to another browser tab, and then back to the Firefox tab that includes the Tabler webfonts, there is a 3 second delay before the tab switches. When we enable the performance analyzer, we find that the delay is almost 100% Reflow of the page, even though the page is static as this point (no changes) from the last time it was activated.

We do not have this issue on Firefox for Linux, MS Edge or any other Chromium browser, only Firefox on Windows. I'm using the latest version 134. Should I be opening a bug?

Computer: Lenovo Y70-70 laptop Phone: Motorola Edge+ 5G UW (2022) OS: Microsoft Windows 10 Home Firefox: Version 134.0.1 (64-bit)

When I awoke my laptop from sleep this morning, the opened Mercari tab did not load correctly, forcing me to log out and attempt to reset it. It acted as if I was not logged in to begin with and would not load the correct account information. When I logged out and then attempted to log back in, I was given an error that stated that the password or account was incorrect. I contacted Mercari Support for assistance, first, as I could not log into my account on an Edge browser, either. When I opened a Chrome browser, it auto-logged me in without issue. Mercari support assisted me for close to 13 hours, and eventually changed my email address associated with my account. Unfortunately, after that, I still could not get logged in, still getting the same wrong password or account message on my laptop. HOWEVER, when I opened firefox on my phone and attempted to log in there, it worked, using the same account and password information as I had attempted on my laptop. Additionally, I was able to log into my Mercari app on my phone, as well as BOTH Chrome and Edge on my laptop. It is only Firefox on my laptop which is not accepting the correct information. I have cleared my cache on firefox, which did not work. I have done an end task on Firefox on my laptop and restarted it, which did not work. I have restarted my laptop, which did not work. I power cycled my T-mobile router, which did not work. I even connected to the internet via hot-spot through my motorola phone, which also did not work. I can log into Mercari on any other way that I attempt, using the same account and password, EXCEPT for Firefox on my Lenovo. Firefox claims that it is up to date and will not find a newer update. Nothing was altered, to my knowledge, between putting my laptop to sleep last night and waking it up this morning. No updates, power interruptions, or anything that I am aware of. I am at my wit's end and am out of ideas for things to try to fix this. Please help. I do NOT want to have to run Chrome again, just to be able to log into a single page on my laptop.

I'm trying to log into this page: https://accounts.firefox.com

The sign up or sign in button doesn't work. The first time I click it, it immediately refreshes. I click again and nothing. On the 3rd click, it just spins for 30 seconds then goes back to being blue. This continues every time I attempt to click further.

I can login on this page just fine using Firefox on my android phone. I can also login using the Edge browser. Matter of fact, I had to use Edge so I could post this issue.

This is a completely fresh install of Firefox, on a completely fresh install of Windows.

I have searched Support, enabled media Autoplay for all sites, Page Info for individual sites. Videos play but never with audio. Currently using FF 134.0 (64-bit) on Debian 12, but recall some problems starting about the 133.0 update. No audio with Youtube, Amazon testimonials/reviews, etc.

Please help?

I'm trying to use a script which requires a question mark after the "dot com." I.e., if the url should be http://www.URL.com?custom_URL, it changes it to http://www.URL.com/?custom_URL. How to I keep it from changing the URL - and what is the point of jamming that slash in there in the first place?

This is my second attempt at getting an answer. Can't anyone help me with this?

When I press a hotkey that involves Ctrl (ie. opening a new Tab via Ctrl+T or closing one via Ctrl+W) Ctrl sometimes remains stuck until I press it again. This will cause issues ie. when I open a new tab and try to type a new address (or search term), and Ctrl causes new hotkeys to be executed.

I've even tried launching firefox with a new profile, and on safe mode (firefox --safe-mode -p <something-else-than-usual>), so no bookmarks, cookies or extensions should be causing this, and it will still happen sometimes. The annoying part is that this seems to be an issue with performance. It happens less-often with the empty profile and safe mode, but it still happens, especially if I had just opened a new page some tab, causing the most minute thing for firefox to process.

The problem is probably not the computer specs either (below my specs). Indeed, from what I can tell, firefox does not even seem to function particularily slow in any case. Just this ctrl being stuck seems to happen.

I have also tried disabling hardware-acceleration (and explicitly enabling it), no effect.

Other interesting facts I've discovered: - This for sure does not happen in other programs and - This does not happen with the Ctrl for all the keybinds within firefox. For example, Ctrl+A (for select all) does not trigger this

From neofetch my setup is OS: Arch Linux x86_64 Host: MS-7C56 1.0 Kernel: 6.12.8-arch1-1 Uptime: 2 hours, 10 mins Packages: 2370 (pacman), 7 (flatpak) Shell: zsh 5.9 Resolution: 3840x2160 DE: labwc:wlroots WM: sway Terminal: alacritty CPU: AMD Ryzen 9 5900X (24) @ 4.951GHz GPU: AMD ATI Radeon RX 7900 XT/7900 XTX/7900 GRE/7900M Memory: 5531MiB / 32015MiB

(I have no idea why it's reporting that I'm using Sway, I'm most certainly only using labwc, maybe labwc just reports sway for some programs for compatibility) I've installed firefox from pacman, and my current version is firefox 134.0.1-1

And finally firefox --full-version Mozilla Firefox 134.0.1 20250113214611 20250113214611

I'm not sure what else I could share at this point

In some pages, redaer view shows the wrong text -- it looks like it picks up text from a hyperlink. An example is this page:

    https://www.britannica.com/biography/Pee-Wee-Russell

where Reader View shows the text from:

(which is linked inside).

I am using Firefox 134.0 on MacOS (Sequoia 15.2)
