Firefox Community Forum

Getting to www.costco.ca impossible during past few days - disabling tracking does nothing! Tried relaxing most security and tracking settings, still no results. MS Edge works just fine, like Firefox used to until now. Guess it's time to switch if no other option.

I am running Firefox 121.0.1, which is currently up to date, on a slightly older MacBook, which has the latest MacOS it can get: macOS 11.6.8. As the title states, YouTube is almost unwatchable on my machine. The video will pause frequently while audio continues, motion is not very smooth, which is especially noticeable watching sports, etc. I cleared cookies and cache, I have run in Troubleshoot mode as well as tried flipping some switches in about:config that I've seen in YouTube videos and forum posts about similar issues, but nothing has solved this issue.

YouTube in Google Chrome works fine, and I've been watching HD YouTube on this laptop with it for years without any issues, so I doubt it has anything to do with machine specs like RAM, CPU, etc.

I was hoping to make Firefox my new browser and start supporting browsers that aren't chromium based since Google Chrome is going too far with respect to privacy and the freedom to use the add-ons I like (e.g. adblockers like ublock origin), but so far I have not been enjoying Firefox for YouTube. Any help would be greatly appreciated.

I've written about this before and never got a working answer. I have to use Chrome or internet explorer for some work because FireFox won't open the sites. This problem hasn't been fixed by I clearing cache and cookies as recommended back when I first asked a year or so ago.

Now the latest website I haven't been able to use is the Post office! USPS.com -- If I try to track a mail piece using my tracking number the site can't bring it up. The site tries for long time then tells me to try later. When I try with another browser such as Chrome, the result is there within a couple of seconds. It looks like I'm going to have to leave FireFox which I hate as I've used it so long - over ten years at least.

Is it possible to combine history/bookmark files? Firefox has truncated my "History" to 15 days and the only option I see to get elder entries is to combine a backupped history file with the current one. An easy-to-use tool for this task would be welcome. I did not change my config options after the update to 121.0.1 (64-Bit) (Windows 10pro) but I think I had the total history (from years) before the update. My current Options related to this topic are: browser.history_expire_days false places.history.expiration.max_pages false places.history.expiration.transient_current_max_pages 501234 privacy.clearOnShutdown.history false privacy.history.custom true history (*) Boolean Number String

I already sreened Help files of this Forum concerning lost history data but they all do not give sufficient answers or I do not understand them (as a German user). Thanks. Martin

Hello,

I have a platform where architects can download digital content in the file formats of dwg (autocad) and ai (adobe illustrator). The site is old and has been working for many years.

Today I received an email from a user that had issues downloading the ai files. I went on to the site an investigated. I am also unable to download the ai files. The dwgs are working as expected.

The ai files are converted to pdf and open in the browser in some web preview. If I then download the file from there it is still, when downloaded to my machine, a pdf. This is not the behavior from before. This is a change in Firefox.

How, when, and why is this change implemented? It seems like a pretty radical change, to coerce one file format to another without any option to get the source file for the user.

Any help is appreciated.

Is it still possible to configure userChrome.css to have the URL field in the Firefox 'Add bookmark' window? Also, is userChrome.css configuration going to be used no more in future releases? If yes, then how will we be able to customize, for example, fonts in Library, side bar and context menu?

Hi,

I cannot logon to icloud using Firefox (since 3 days) on my windows pc. It normally works fine

I can logon on using the mobile firefox browser and I can logon using Edge. However, I don't want to use Edge

I use a VPN (including browser extension) but I haven't had a problem before

Thanks

Jonathan

I view a lot of pdf documents via firefox, the light gray background makes my eyes and head hurt after prolonged usage. In the past I found a solution on this forum that advised to set pdfjs.viewerCssTheme to "2" in about:config. This set the background of pdf viewer to black/dark gray. This has worked for years until recently when the pdf viewer switched to light mode again (pic 1). I checked the about:config settings for pdfjs.viewerCssTheme but there appears to be no change. I tried restarting the browser, setting the theme to 0 and to 2 again, updating browser. Sadly the theme is still light gray. Is there a way to change it again? The desired outcome is in pic 2. I do NOT want to change the color of the pdf pages themselves.

Hello, Why does Firefox (121.0.1 (64-bit) macOS 14.2.1 anyways) apply a gradient color overlay to the Business Logos in Google SERPs?

I.e., typically the website's Favicon is pulled or an image written into Schema data to display the company logo next to the search result excerpt. But lately, and apparently only in FF, the logos are discolored by some kind of overlay?

Please see attached comparison between Chrome and FF. Chrome displays the logos unaltered, and FF displays them with this crazy obnoxious overlay/ color correction.

As far as I can tell, this is coming from FF as I don't see it in any other browsers/ devices. Chrome, FF Developer Edition, MS Edge, and Safari do not alter the logo colors.

Is there anyway to request the Mozilla FF stop doing this? I can't possibly begin to imagine how this is helpful in anyway to users... but of course I'm open to hearing any logic behind this decision, if in fact this is coming from FF.

Thank you all for your time and help!

Hi

I have been using Firefox for years and never encountered this problem. I changed the theme to dark but it made some websites unreadable, so I changed it back. The problem is some websites did not register the change. I cannot use these websites anymore with your browser, and I would prefer to stay with Firefox. What can I do? I have changed the system settings and Firefox settings. Nothing has helped. I have gone through your troubleshooting advice and googled various topics to figure this out. Nothing. It is frustrating, especially when one of the broken sites is my work portal. This cannot continue, so I will be forced to change browsers. I use both Mac and Windows computers if that helps. It is the same on both.

Cheers, George

Despite reading almost 100 questions about this exact issue asked for years, there still seems to be no answer, and no fix to get this function to work properly.

Checking the box should completely remove the drop box for location, and the entire point is that it should ask you where to save every file,instead of defaulting.

Using Firefox View, I am unable to view my tabs from other devices after setting up Sync. It is saying Check your internet connection. If you’re using a firewall or proxy, check that Firefox has permission to access the web. as if I don't have a correctly configured connection. However I indeed do and am able to browse the web without any issues. I should mention that I'm running the latest stable flatpak and I'm wondering if this could be related but I have no idea how to manipulate the flatpak to make this work.

Hello Mozilla Support,

Since 2 upgrades ago, anytime I try to watch a livestream, my browser slows right down and then crashes.

I don't care why its happening, I just want a definitive fix for the issue.

I'm so aggrieved at this happening constantly, if you cannot provide a firm resolution to this issue, i will simply move to another browser.

I've tried your about:config setting restart to false and other fixes but still keeps happening.

I await your reply.

With Regards,

Mark

I recently traveled to Australia for two weeks. While there, I used my mac laptop (with Firefox as my primary browser) on a mix of both wifi-without-VPN and hotel wifi with a VPN back to my home network activated.

I have been back home for more than a week. Other browsers on the same laptop as well as other devices (like my phone) that I took with me on the trip correctly reflect my location (east coast, USA). However, Firefox stubbornly insists that I am still in Australia. The net effect of this has been to break my access to YouTubeTV, which is not available in Australia.

I have tried: - Logging fully out of my google account on firefox and logging back in (at which point the 2FA prompt on my phone says I'm trying to log back in from Australia) - Deleting all cookies, cache and website data - Fully uninstalling Firefox, including deleting the Firefox folder in ApplicationSupport

None of these have had any effect.

Within YouTubeTV, I can force an update to my location, which will temporarily reflect correctly that I am in the US. But it still won't let me play anything if I'm using Firefox, and within Firefox, will soon revert to location unknown. Other browsers on this laptop, and other devices, work fine.

I am at my wit's end. Please advise.

The Amazon.co.uk search plugin was working but now its not and when i try to click "add search engine" a box pops up with

Firefox could not download the search plugin from: https://d2lo25i6d3q8zm.cloudfront.net/browser-plugins/AmazonSearchSuggestionsOSD.Firefox.xml

another post suggested checking the about:config browser.search.region mine says "GB" which would be correct for .co.uk

All other search plugins work fine. Any suggestions?

I've always liked the Firefox New Tab page, with Pocket, and until today, DarkReader plugin has always worked. But now it says that it can't because the page is protected.

I tried the solution to use bookmarklets, suggested in https://support.mozilla.org/en-US/questions/1350781, but it didn't have any effect (https://sanketmehta7.github.io/DarkMode-JS-BookMark/

If I can't find a solution, I'll just ditch Pocket, and use Google as my first page, or something. Or maybe ditch Firefox, which doesn't seem to think that dark mode is important. I don't like being blinded by the light.
