Firefox Support Forum

I am using Firefox browser with DuckDuckGo search engine. When trying to print a crossword puzzle daily form USA Today, I get the following message after pressing the play button: Application error: a client-side exception has occurred (see the browser console for more information). If I refresh the page, the site continues on and lets me print the puzzle. I tried switching back to Firefox for the search engine with the same result. This issue does not occur on Google Chrome, however. I have included a screenshot of website when error occurred. Thank you in advance.

Dear Firefox Team, good morning.

I hope you are doing well and that you are all healthy.

Guys... while looking for a way to measure the performance of our site, we came across the Core Web Vitals (CWV) some time ago. These are Google KPIs for measuring the user experience on a page (https://web.dev/vitals/#core-web-vitals). Unfortunately, some of the KPIs (like the Largest Contentful Paint or Cumulative Layout Shift) are currently only accessible using Chrome and it's preformance API. That's a pity, because there are also many people using Firefox who visit our site... and it would be interesting to have such KPIs as well.

In an article by Cloudflare (https://developers.cloudflare.com/analytics/web-analytics/understanding-web-analytics/core-web-vitals/) we recently learned that Firefox is also planning to expose the metrics used in the CWV... only the "coming soon" from the article is a bit vague. That's why I'm contacting you to get some more information on that topic. Do you perhaps know whether the topic is planned and will be tackled this year?

Thank you for your attention. Best regards, Carlos

I am unable to sign into Microsoft 365 services in Firefox. When I try to sign in on the Microsoft 365 Website, it doesn't sign in, it simply redirects me back to the website. When I try to sign in from the Outlook login page, I get an error page saying "500 Something went wrong. Repeating redirects detected." Screenshot attached.

1. I was able to sign in with another browser. 2. I was able to sign in on a device running Windows 10. 3. I have cleared the entire cache and history on the Firefox browser - it didn't work. 4. I tried logging in with Firefox in Troubleshooting Mode - it didn't work.

I saw an archived thread from 10/28/2021 where @OthelloBloke had the same issue ("Microsoft 365 Signin on Office.com Doesn't Work After Windows 11 Update"). It didn't seem to have been resolved. It has been a while since Windows 11 came out. Has there been any resolution to this issue? Please help me fix it. Most of my activities are on Microsoft 365, and I prefer to use Firefox as my browser. But if this is ongoing I will need to abandon this browser in order to access my work.

For the last few months (perhaps concurrent with a Firefox update, but I don't remember), Firefox seems to be having problems with Google-sourced stuff. It's intermittent, but the most frequent failures are searches using either the address field or the dedicated search field - much of the time I just get a blank page, and at first it looks like it might be trying to load something, but after awhile the "X" abort icon changes to the reload icon, signaling that it thinks it is loaded or has given up. Success or failure seems to come in waves or phases, not completely random - immediately retrying will usually not work. If I can get to the Google home page by typing "google.com" directly (which has a much better batting average than searching in the address/search fields, although not always), I can search directly on the Google page without trouble for some mysterious reason (perhaps that fills the page using AJAX rather than reloading - I'm not sure). But then clicking on one of the results might not work, because that initially goes to a Google URL before redirecting to the requested page. I've resorted to extracting the page location from that redirection URL just to bypass Google.

Other Google services have problems, too. YouTube's home page usually loads outlines of videos, but sometimes it fails to fill in thumbnails and other details or does so VERY slowly. Occasionally even reCaptcha will fail to load when I'm trying to log into some site that uses it. And even when something appears to fully load and function (e.g. a couple Google Sheets I use daily), often the "stop loading this page" X and hourglass on the tab will remain, indicating that it thinks something is still loading (in that case, it seems to never time out - I either click the X or ignore it). All these types of failures started at the same time, so they seem to have a common cause.

I have not noticed any problems with sources that are not owned by Google. And Chrome and Edge have no problems at all. So apparently it's specifically Firefox and Google that are not getting along. I'm running Firefox 108.0.1 (in PortableApps, although located on my hard drive) on Windows 11.

These failures happen even if I start Firefox in troubleshooting mode (which proves it's not caused by an add-on) or open Google in a private window so that there are no cookies involved. Since Chrome works, I also tried using the User-Agent Switcher add-on to pretend I'm Chrome, but that also has no effect. I expected to see tons of other complaints about this on the web, but there have been surprisingly few, and the only suggestion that seemed relevant (and effective for some people) was to set "security.tls.enable_0rtt_data" to false, but that has not made any noticeable difference in my case.

I waited through a couple Firefox updates, hoping it would just get well, but I've lost patience. Are there any new ideas out there?

I have firefox 108.0.2. I have enabled the Block pop-up windows option. I have a local file that open popups (file:///local_path/a.html). When I open the file I get a notification that pop-ups are blocked. I try to put an exception in Block pop-up windows with the path: file:///local_path/a.html, but does not work (warning still appears) How I can do it?

When you open a web site, a tab is created up top under the "File," "Edit," "View," etc. tabs. And, obviously, if you have more then one site open, they're all there. But this week I noticed that with the fourth tab, they stop being visible, and there's arrows on the far left and right. So if you have five or six pages open and you want to go back to the first tab/web site, you have to hit the arrow on the far left to make that tab visible, and then click on the tab.

So they went from one step/click to two, or three, or four! Sometimes I have to click around to find the tab I want. Also, there's times I just want to see if a site/tab is there. Now, I have to click the darn arrow and find it!

Why do they do this? If it aint broke, don't fix it!

I don't want it like this. At all. I want all the tabs there, without any arrows. Just like it always was. How do I get it back to what it was?

Hi,

I'm having trouble connecting to a specific webpage on the internet.

The link is: https://www.canadiantire.ca/en.html All I get is a blank page.

It is a popular retail chain store in Canada. I know the website is up and running because I can connect to it using another PC at home.

How do I check what messages are sent from my FF browser to the website?

And then - what is received at my browser from the website?

BTW - I have cleared the cache and restarted FF - and still cannot connect to it. There are 3 other websites that I have trouble displaying and interacting properly. How do I know this? - Well - I tried the 3 other websites from other PCs within my home network and these websites work properly.

Hello there; I had installed the "savefrom.net" extension. This extension automatically generated the website address to the "bookmarks toolbar". I deleted the extension and deleted the shortcut as well. But when the bookmarked website shortcut "firefox" is closed and reopened, it adds itself to the bookmarks toolbar again. No matter what I did, it didn't work. I don't want to delete Firefox completely and reinstall it. Because there are too many shortcuts and data that I use all the time. How do you think I can solve this problem?

52.9.0esr is claimed to be the last version for XP. Unfortunately it is not quite true. It is for XP SP2 ONLY. Trying to install on SP3 ends with the message that SP2 is required. IMO the installer is simply too strict on demanding exact version of SP ! https://www.mozilla.org/en-US/firefox/52.9.0/system-requirements/

I went through the list of versions (thanks Mozilla that they all are still available!) and found that the last version I can install is... version... 12.0b6. https://www.mozilla.org/en-US/firefox/12.0/system-requirements/

And indeed I installed 12.0b6 successfully but I would like to install 52.9.

I am prevented from downloading an important document because the site says that I need to disable an ad blocker. I am not aware of having an ad blocker and nothing shows up in add ons and extensions. How do I find and disable an ad blocker that I cannot find?

I can connect bluetooth devices to my SurfaceGo and successfully direct audio output to them using Chrome, Edge, or internal sound files. But in Firefox the audio only goes thru the internal speaker no matter which audio output device I select. Is there some setting I need to fix so that Firefox will speak to bluetooth devices?

Hello all,

I'm running Version 108.0.1 on a mid 2015 Macbook Pro MacOS 12.6.2 Today I went to do a translation using the "to google translate" add-on and noticed it was missing from its place in the context menu. I go to "get more add-ons and re-installed it.

So why was it uninstalled without my consent? What can I do to stop this happening again?

TIA, Gene

Hi, I just replaced my SSD (Samsung 960EVO m.2 250Gb) for a larger/faster SSD (Samsung 980 m.2 1Tb) . I'm on Windows 10 and have 32Mb Ram. Firefox is now very slow on some websites (not all).

This example is typical and has occured on multiple sites. To test and compare, I copied the URL, created a new tab in Firefox, then Paste and Go. I timed this 3 times and each time was 30 seconds. I Pasted the same into Chrome and Edge and each time it was instant. https://savingschampion.co.uk/best-buys/personal/easy-access-accounts

On my previous SSD, there was never an issue of any lag on any site.

BBC.co.uk/news is fine, as are several other sites. Does anyone have any idea what's happening? This is making Firefox unworkable for me, so unless I can fix the issue, I will have to move permanently to Chrome or Edge. That would be a shame after many years with Firefox.

Thank you in advance.

When I tap the middle mouse wheel to enable auto-scrolling (with no additional inputs like clicking, scrolling, or keyboard inputs), on release of the middle mouse wheel, auto-scroll disappears. I can only use auto-scroll while holding down the middle mouse wheel.

I've reached out to other's and this seems to not be the intended/default behavior. I've confirmed middle-mouse wheel scroll (where it's a tap / toggle) works on Chrome as well as other applications like Spotify.

I would like to have it as a toggle. What can I do?

I have run Firefox for years on up to 4 PCs at once, everything has always synced and screens all look the same. Recently one laptop lost the addon extension icons in the Firefox toolbar. They remain on all other installations. I have tried uninstalling Firefox and installing an earlier build, and also the latest Beta build with no luck. All extensions show as installed and activated. I have copied the Profile from another laptop. I have of course done a reset. Any other suggestions?

Getting unreadable text when website is using a font that isn't installed (see attached screenshot). When I view the source in developer tools it uses Roboto (which I haven't installed).

On my Mac, I have tried other browsers (Chrome and Safari) and they work fine. I have also tried this website with Firefox on Windows and it also works fine.
