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?

As of February 13, 2025 the front page of the Washington Post website does not load correctly in Firefox 115.20.0esr in Mac OS 10.13.6. The problem persists even in safe mode. Thank you.

Suddenly this morning Firefox stopped connecting to any websites. It never gives an error message, it just tries to connect forever. Chrome and Edge can both access the internet without problems. I'm running Windows 11 Pro, and here's what I've tried so far:

Malwarebytes disabled Firewall disabled Turned off all add-ons/extensions Firefox uninstalled and reinstalled Firefox, Windows, Malwarebytes, etc all updated Cache & cookies cleared Refresh Proxy use disabled IPv6 enabled DNS prefetching set to "true" Full malware scan by Malwarebytes Computer restarted (several times)

Any other ideas? Thanks!

12/12/24 - netflix says i need to upgrade firefox browser in order to watch vis, but running MOST current version (115.18.0esr). Mac OS 10.12.6 . need help fixing issue. thanks

I am having difficulty trying to view a website. I receive the following message whenever I try to view this website:

"Suspected Phishing This website has been reported for potential phishing.

Phishing is when a site attempts to steal sensitive information by falsely presenting as a safe source."

There are two buttons beneath this message, the one on the left which reads "Learn More," the one on the right which reads "Ignore & Proceed." Yet when I click on either of the buttons a blank white page appears.

The web address in the URL field also changes from the website I originally selected to the following:

Why would I not be able to view this website (and others too) with Firefox but am able with Chrome? I want to be able use Firefox, as Chrome will not allow use of an extension that Firefox will.

Please tell me how this problem may be fixed.

I got a Firefox update recently and have not been able to access Flickr since then. I am getting a message that the page is not redirecting correctly. I am attaching the error message. I am running with standard firefox protection. I have cleared cache and cookies. I have also added Flickr as an exception to Firefox enhanced privacy tracking. Firefox is up to date (version 134.0.1 (64 bit)). Anyone else having this issue or know the solution?

I'm using Mac OS 11.7.10. Firefox desktop no longer allows me to browse the internet. It just keeps spinning wheels. I've downloaded the newest version and it still crashes. What can I do?

Working on setting up a new PC build. I've had to use some PC support website chats and many of them have just not acted right? For example, one would allow me to start a chat but then sent me directly to closing the chat like we were finished. The others would lock up my Firefox many times. Anything come to mind as to why this is happening? Windows 11 Pro v24H2 and latest Firefox version.

Hi,

I have donated to Mozilla Foundation in the past and will gladly do so again once a vexing issue has been resolved. I am using the latest Firefox version for Mac.

While using the updated Mozilla Firefox recently I find that allthewordsItypesticktogetherlikethis when I try to search for something. It can also happen when I type emails using Firefox. So I often have to change back to Safari.

Also, I notice that with the updated Firefox version, a mysterious blue square appears around the text I am working on.

Do you have any suggestions or instructions as to how to stop the annoyingjoingingtogether of words from happening? Please help!

Thankyou!

Firefox is no longer compatible with my bank's system. I can't log in with the secure access code the bank sends to verify my identity when using Firefox. The bank says it is a problem with Firefox. Other browsers work flawlessly ... are you working on a solution? I only use Firefox unless forced to use something else ...

i AM RECEIVING EMAILS ALL DAY LONG FROM SECUREDJOINTNETWORK TELLING MY SYSTEM IS INFECTED.. MY SECURITY PREVENTS THAT i WANT THESE NOTICES STOPPED, BUT DON'T KNOW HOW TO DO IT.

If I visit the website www.silviadesimone.it (I am the webmaster) through Google Chrome or Microsoft Edge, I can see the visit counter in the left bottom corner of the page. If I use Mozilla Firefox (that is the browser that I normally use) the visit counter does not appear. According to the ShinyStat helpdesk it could depend on some Firefox plugin that does not allow the counter to show. Can you help me? Thank you

When I try to sign into eBay, a multi-photo comes up asking me to identify like objects in order to be allowed to enter the program. I believe Firefox is causing this problem. How can I fix the problem?

Hi,

The scouting association have updated their members website to membership.scouts.org.uk. This works, but from there is a link to my learning.scouts.co.uk. Sometimes this works but often I get "bad request, error 400". I've had to move to Edge when using this website. I didn't want to! I've used Firefox for years

Whenever I login to the web site "SSA.GOV" and click the login button, the next screen presented in Firefox is: "Bad Request

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

If I go to a Private Window, type in the SSA.Gov and then select the Login page, I am presented with the correct page and can then supply my information and login.

Observed:

I use Firefox 133 on Mint 22, I have 2 browser profiles. When I access Atlassian Confluence (any confluence page under atlassian.net), the page content is loaded, but then disappears and I get the following error at the top of the page: "This page was in the background for too long and may not have fully loaded. Try to refresh the page"

This only happens in one browser profile: in the other, all the pages open correctly and quickly. When I open a private tab using the problematic browser profile, again all the pages open correctly.

I have tried clearing all atlassian.net and atlassian.com cookies and data from the browser privacy settings, disabling all extensions, restarting the browser, even restarting the computer, but to no effect.

Expected: Confluence pages should open using any browser profile.

Reproducibility: 20+ out of 20+ attempts

Workarounds:

Temporarily use the other browser profile or a private tab, although that way I don't have the benefit of using browser history and if I kill the browser while using private tabs, private tabs will not be restored, so I lose track of what I was working on. I could use a different browser for confluence, but that has the same history problem and is generally senseless: Confluence should work correctly using any browser.

Notes:

I have seen similar issues 3-4 times before with Confluence, but it was always due to extensions, so disabling the problematic extension or configuring it to ignore anything related to Atlassian was sufficient. I would report this to Atlassian, but they'll just say "it works with a blank browser, so it's not our bug" and they're probably right. There's some kind of Atlassian-related state being preserved in the problematic browser profile, but I can't pinpoint it, so any help there is welcome.
