Can't event imagine how to debug this - FF has stopped working totally from the command line, despite options etc It is still working when run from the dock however. But I need to start it from the terminal for the second profile

Myself and a colleague who both use Firefox on Mac are experiencing the exact same issues.

1. Table header cells don't show their text, unless we specify a font for the table

I tried to put an example of the HTML here but it was rendered as a table by this page. I'll add some images of the code instead to show it.

In Firefox the Header cells are not visible, but in Chrome the text appears correctly.

If we add CSS like...

<style> table { font-family: Arial, Helvetica, sans-serif; } </style>

...in the header then the missing text in the THs appears.

2. Other font issues

The Wave accessibility extension has text that doesn't appear and throw errors like this in the console...

downloadable font: rejected by sanitizer (font-family: "Open Sans" style:normal weight:400 stretch:100 src index:3) source: moz-extension://b86260c9-33f6-4529-b12f-a101d8607bd4/styles/open-sans-v17-latin-regular.woff

These only occur on Firefox on our Macs. Fine on PC and other browsers on the Macs.

We tried a whole series of tweaks to settings to try fix this.

I have tried resetting Firefox and doing a fresh install but nothing fixes either issue. Are these known issues with recent Firefox releases on Mac?

As of a few days ago whenever I start Firefox the window appears with the Bookmarks sidebar panel already opened. I click the "X" on the sidebar and it will close - until the next time I start Firefox. If I choose Menu->View->Sidebar->Bookmarks and uncheck it the panel will close - until the next time I start Firefox. No matter how the Bookmarks sidebar is closed, it will always reappear when Firefox is restarted. Even if I switch to some other sidebar, Bookmarks will replace it on startup.

I've searched about:config and found no setting which seems to control sidebar behavior on startup.

I assume this is the result of some recent update. Is there no longer a way to permanently disable the Bookmarks sidebar?

MacOS 12.7.5 Firefox 127.0 (64-bit)

macOS 15.6 Firefox 141.0.3 - my preferred browser

I've seen a number of posts regarding this problem since the Firefox 141 update. I've tried a number of suggestions, although my problem seems slightly different.

I can apparently login to reddit OK but when I try to access a subreddit thread, a warning comes up - see image.

I have cleared Firefox site data, cookies, cached files, etc - problem remains.

I have restarted Firefox in Troubleshooting mode - problem remains, so not an extension.

However, https://old.reddit.com has no problems with Firefox, lets me access threads, etc and comment.

No problems accessing reddit with Safari or DuckDuckGo browser.

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.

For some reason all of a sudden my bookmarks don't show their identification icons that are associated with that web site. Those icons are to the immediate left of the site address. I used to use those colored icons as a quick reference to select the web site I wanted. Being I have MANY bookmarks, those icons to the left weer a GREAT help to locating a specific bookmark.

   How do I get my bookmarks to show the way they used to show before? Is there a way to show my bookmarks to a earlier date? Maybe that way my bookmarks will show the way they used to ?
   Can someone please help. This new bookmark menu listing I now see is not user friendly! Thank you.

Hello! Like many before me, the tabs crash every time I got to YouTube. The only message I get is

"Gah. Your tab just crashed. We can help! Choose Restore This Tab to reload the page." This option does NOTHING to solve the issue.

Not sure why, but I've never had this issue before until about a week ago. I don't want to use another browser. I prefer Firefox.

I am currently using Firefox 121.0.

Any information/assistance would be greatly appreciated.

Thank you!

I am old-school security conscious & have been using FF since its inception. Really. Clear my cache & delete browsing cookies on a regular basis. I use a private window for shopping and q&a info gathering. Recently I saw Walmart.com showing up in my cookies and couldn't figure out how/why as I *only* look at Walmart in a private window. Today I realized Walmart has managed to bypass the private window options and place cookies anyway! To say I'm furious about this is an understatement. I have adjusted my settings to "Strict" but it's still able to bypass the private window and is staying on my computer. I am updated to the most recent FF version; running MacOs Sonoma 14.7.7 which was just recently updated; I'm not going past this one for now but that really shouldn't be the issue. This is most definitely a FF issue and one that needs to be rectified not just because it's Walmart but because if they can do it so can others soon enough. This cannot stand.

In my location, my only option for internet access is a mobile hotspot with limited data. Consequently, I am always mindful of my data usage when using my laptop. Despite primarily browsing static pages, email, and other low-data activities, I often find my data usage higher than anticipated. The main culprit comes to mind to be videos embedded in news articles. Sometimes, with multiple tabs open, I switch to an inactive tab only to find a video playing. Although I've configured my Firefox preferences not to autoplay videos, it seems that YouTube videos still override these settings.

So, my question is, when a tab is inactive, does Firefox stop all data transfer for that tab in the background? And if not, what are the solutions to stop any background data other than continually closing all tabs?

Also, any suggestions on this topic are appreciated, especially from and to users who also live in remote areas without fiber, DSL, etc.

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.

There is this new pop up coming on latest firefox version 123 about opening favorite link on firefox, I want to get rid of it programmatically using java, which argument or preference should I use ?

Hello,

I use the Firefox browser on my phone and laptop, and have Lockwise on my phone where all the passwords are stored. Until yesterday, all these passwords would always appear in my Firefox browser stored passwords. Now, they only show up in Lockwise on my phone and do not show up in the phone or Laptop Firefox browser.

I have followed this guide: https://support.mozilla.org/en-US/kb/end-of-support-firefox-lockwise and am syncing passwords across devices, but this did not solve the problem.

Has anyone else encountered this and know how to fix it?

Thank you.

On my old iMac, Firefox remembered sites I had visited and filled them in, like if I typed A it would autofill Amazon. This is not happening on my new 2023 iMac and I can't figure out how to turn this on. Also, I could see my site visit history on my old iMac, but this field is blank, with no history of sites visited shown, on my new machine. Help is appreciated. Please keep in mind that I am technically retarded and need step by step guidence. Thank you in advance for your help

Hi there,

Using up to date Firefox on a Mac, London UK. Recently returned from travel in Japan. The bank cards auto-fill stopped working & Auto-fill does not appear in Privacy Settings (it is not there – no need to request a check please:)?

Spent 2 hours on Mozilla support/community etc. No answers – including 'make a new profile'...(& why - won' that affect history etc)?

Would be very grateful for any help please?

With thanks,

Alex

I just updated my iMac from Mojave to Catalina 10.15.7. I thought Firefox would provide an update to convert the esr version to the standard Firefox browser since I am no longer using Mojave, but the next update is 115.15.0esr. Is that correct? My understanding is that the esr updates are just for computers using older operating systems through Mojave. I did not update to 115.15.0esr since I am not sure if that is the right version for Catalina. Any information and assistance you can provide me is greatly appreciated. Thank you.

Seems like when I tried logging in to my old account with a password reset, I somehow created a second account with the same email.

All my bookmarks and extension set ups seem to be gone.

Never had this issue, and have been using the same firefox account for like 5 years.

Bookmarks Sidebar Automatically Opening. Please advise how to stop. Suddenly started happening once before [April 7, 2022], self corrected itself. Happening again [April 6, 2024]

⬛️ When right clicking Firefox icon in dock to open new window,

    New window opens with bookmarks open.

FF Version 124.0.2 Thank you for your time and help.

I got a new Macbook Pro recently and set it up by basically copying my iMac onto it. All works great. Except that the MBP doesn't show up with it's synced open taps on my iMac or my iphone. The iMac doens't show up on the MBP either.

Have I maybe copied some setting that makes the two machines (iMAc and MBP) thinkt they're one and the same? How can I "separate" the devices so that they show up in each other's Synced Tabs lists, respectively?
