After using the "recent browsing" menu in the top left corner of FF and opening certain websites from the "import tabs from other devices" menu it has completely broken a handful of websites on my PC entirely, even using other browsers.

The page will load but no content is displayed, no links or media, just a blank white page. This is consistent among these websites even among other browsers including Chrome and Edge.

I have uninstalled and reinstalled FF multiple times, cleared cache/history, hard PC resets, refreshed FF, Uninstalled and reinstalled every browser. The issue persists.

These websites still function perfectly fine on mobile FF and Chrome. I've exhausted website permissions, app permissions, etc. The issue still persists. These websites were functioning just minutes before I tried importing them from the other devices tabs. Something about that functionality has completely broken them on my PC.

This question relates to version 134.0.2 (64-bit). This morning I started Firefox and found that many of my bookmarks were missing. On trying to restore from the program automatic backups, I get the repeated message "Unable to process the backup file." On examination, the files, while not in ASCII, appear to contain ASCII text strings recognizable from the bookmark descriptions. They are not, at least, empty. Unfortunately, I do not have an HTML format backup. Any idea why none of the backups work or what options I have? Thanks in advance.

The logo in the top left-hand corner of my website's landing page does not display using Firefox but is displayed properly using every other desktop browser. Using Firefox, just my name is displayed in place of the logo. Chrome for Android has the same problem but Firefox for Android displays OK. On my iPad both Chrome and Firefox display properly. What are the reasons for this? Is there some upper limit for the dimensions of the logo (mine is oblong in shape)? Do I have some settings that don't suit certain browsers? My site was built using Wordpress/Elementor/OceanWP. Many thanks in advance for an answer!

A video of what is happening . This only happens when I search something up, for example, if I search more than one thing up on Pinterest, Google and sometimes Youtube . . . I'm sure it's not related to any extensions, the only one I installed recently was Privacy Possum, but after noticing this issue I deleted it and it didn't resolve the issue.

Online purchases only work on about 50% of the websites I buy on. The most recent one was buying a gift card from Whole Foods. This is becoming so ANNOYING; before I finally switch to another browser, does anyone know how to fix this?

I've been having a problem with FF for the last two weeks. At times downloads accessing web sites are slow or even get hung up. Usually reloading or refreshing the page fixes the problem. I tried a FF safe boot and things seemed to work better. I have had the same four extensions for quite awhile. Are there any reports of UBO causing issues?

I use Firefox 134.0.2 (64-bit) on Ubuntu 24.04.

Some (not all) web sites show up only after a delay of exactly 30 seconds. The attached screenshot shows that this delay is due to DNS resolution. This behavior is reproducible by simply closing Firefox, opening it again and entering the same web site once more. Once this initial delay of 30 seconds for DNS resolving has passed the web site can be browsed normally.

Using Google Chrome, Opera or even the Tor Browser on the same system works without any significant delay. Also a DNS lookup from the console returns data almost immediately.

As the delay is always exactly 30 seconds this looks like some DNS resolver timeout only showing up when using Firefox.

Neither starting Firefox in Troubleshoot Mode nor (as often suggested) disabling IPV6 for DNS by setting network.dns.disableIPv6 to true did help.

Any idea how to fix this 30 seconds delay?

Many thanks for any help, Felix

For the last day I've been having a problem with FF slow to load. I've tried the troubleshoot mode with little change. When it does load I can have problems with certain web sites loading e.g. Youtube, MSNBC, AOL mail etc. It's never consistent. The cache is clean and I've saved all the relevant cookies, I checked my internet provider and they are having no problems and I don't seem to be having any internal hdw issues e.g. ethernet cable connections etc. I reinstalled FF-not a clean install and seemed to help for a time. Do I have any options other than a refresh? I don't seem to be having the same issues with Edge or Chrome. All W11 updates are current. I look forward to anyone's comments.

I've used Firefox for many years. The past month or so weather radar doesn't come up on multiple weather sites, pages are slow to load or don't load, getting error codes on video's, pictures don't always load, and many other problems. I uninstalled Firefox and re-installed the current browser and I still have all these problems. I'm having to use another browser now. I run Windows 11 on my PC.

There's a bug with Firefox 134.0.2. where I keep getting logged out of certain websites, even without clearing my cache.

Is there a possible fix in the works for this issue?

When I attempt to use Firefox autofill for address/credit card/etc, Linux will prompt for Root password. After entering root password, everything freezes. I have no access to mouse or keyboard and my entire OS become unresponsive. Besides the hangup, my firefox tabs randomly crash as well with the following bug tag: https://crash-stats.mozilla.org/report/index/3020d645-af46-4821-bbfc-e4d680250213. I don't know if the two are related, but both eventually lead my my OS freezing with only hard power down. Every time I try to use autofill, it freezes my OS. I can keep replicating the issue.

I cannot do online banking with the Bank of Montreal using Firefox. A website (https://thebao.ca) does not display properly when accessed with Firefox.

https://shop.sportsbasement.com displayed and work 3-4 days ago. Now blank. https://us.muc-off.com/ blank https://www.asp-usa.com/ blank https://byrna.com/ blank

I have cleared cashe, history, Turn VPN off, Turn adblocker off, these were all on when it worked. Now nothing

I'm trying to access my https://mypay.dfas.mil account, but, though previously all was well, now an error message tells me that you "can't connect to the server".

I have a network connection, but apparently Firefox may no longer have "permission to access to the web". I'm sure this is wrong because I can still access pretty much everything in the normal way, including other government sites, such as Social Security, using the Login.gov portal, though mypay is not listed as 'connected.'

What happened, and how do I fix it? Also, the error message says that I should "Check that Firefox has permission". How do I do that?
