Using Firefox 17.0.1 on MacOS Ventura 13.6 on my 2017 iMac I am unable to connect to the internet while using Private Internet Access (PIA) VPN. All was working normally until I installed MacOS Ventura 13.6 yesterday. The VPN works normally when using Chrome or Safari. I have tried changing my network proxy setting without any luck. The default setting is "Use System Settings", using No Proxy or Auto Detect Proxy doesn't help. I don't see a switch for Enable DNS over HTTPS. All works fine when the VPN is disabled. I tried deleting the VPN a couple of times then reinstalling but that didn't help.

What am I missing here? I have used this VPN for years without any issues & it worked on Firefox until I installed MacOS 13.6...... using 13.5 I had no problems. Any suggestions or thoughts would be appreciated.

Thanks...... Brad

I have Mac Pro 2018 and having a problem with Thin Lines on left side of the browser (Firefox Mac) i can't find anyone on line with same problem explaining how they resolved the issue!

I am trying to solve a problem with opening a URL from an external app when Firefox is not already active. The issue appeared a couple of years ago. I found it using LaunchBar, but I can reproduce it from a terminal (at least LaunchBar is not to blame).

1) If Firefox is active (I mean, has been launched) and I type the following in a terminal window open 'http://www.mozilla.org' then Firefox opens a new tab with mozilla.org (same with any other site).

2) However, if Firefox is not active (for instance, it has just been quit) and I type the same command in terminal, then Firefox launches, reopens previous tabs, but opens no new tab, thus failing to open mozilla.org (which is what I want).

I tried refreshing (could not try safe mode because the activation of Firefox should be triggered by the terminal command). I also tried uninstalling + fresh copy of Firefox, but as soon as the sync with my mozilla account occurs the problem comes back. I even tried to delete my Mozilla account and recreating a new one, that did not solve the issue.

Note that when I try (2), I sometimes very briefly (1/10 sec) see a new Firefox window open with the right site (mozilla.org) and this window disappears.

The setting for browser.startup.page is 3 and no plugins at all (fresh install, account wiped).

Any help is welcome...

Dear Sir/Madam:

I am using Firefox Browser 102.15.1esr (64-bit) on a MacBook Pro Ventura 13.5.2.

I have been using the www.dictionary.com website for a long time, but recently when I attempt to go there, I keep getting the error message as follows:

Unexpected Application Error! FM.findLast is not a function

WM@https://www.dictionary.com/client.e12a2de6.js:36:305976 $o@https://www.dictionary.com/client.e12a2de6.js:1:26519 ka@https://www.dictionary.com/vendor.60d89d9a.js:1:864941 xu@https://www.dictionary.com/vendor.60d89d9a.js:1:921923 bc@https://www.dictionary.com/vendor.60d89d9a.js:1:910907 yc@https://www.dictionary.com/vendor.60d89d9a.js:1:910835 vc@https://www.dictionary.com/vendor.60d89d9a.js:1:910696 ic@https://www.dictionary.com/vendor.60d89d9a.js:1:907503 oc@https://www.dictionary.com/vendor.60d89d9a.js:1:906055 E@https://www.dictionary.com/vendor.60d89d9a.js:1:996565 P@https://www.dictionary.com/vendor.60d89d9a.js:1:997096

I tried clearing caches under Privacy & Security, but the problem persists.

(Meanwhile, I can visit www.dictionary.com on Safari and Google Chrome.)

Could you please let me know what is going on?

Thank you,

A few days ago links in messages stopped working in Outlook (Microsoft 365) on my Windows 10 Pro 64-bit PC.

Good ol' Microsoft support reset Firefox on the PC and I lost all bookmarks, history and personalized settings. Tried to copy data from Old Firefox Data file into profile on reset Firefox. Didn't work. Uninstalled and reinstalled Firefox and tried to copy data from old profile to new profile. Nada.

Only option now is to try to sync Firefox on my Mac to new install on PC. I'll still lose some bookmarks and history but it will be better than what I have now. I have a Firefox account on both devices but when I log in to Firefox on the Mac I cannot find anything pertaining to sync.

Problem one: how do I navigate to sync in Firefox for Mac. Problem two: when I bought the Mac 6 years ago I tried to sync Firefox on my PC to the new Mac. For some reason Firefox synced the empty new profile on the Mac to the old PC. I lost all bookmarks and history accumulated on the old PC! I do not want to go through that again.

I have never found anything on Mozilla that clearly explains how to control which way the sync works. Must be certain that I'm copying all the bookmarks, history, tabs etc, from the old device to the new on and not vice versa.

Hi! I have two Firefox accounts, one for work and one for personal use. I often have them running on the same computer at once (this does cause them to crash occasionally, but not often enough to be a problem). However, today I tried to log into a website where I regularly do freelance work and received this error code: "Error code: SSL_ERROR_PROTOCOL_VERSION_ALERT"

I would assume something was wrong with the website itself, however when I went to that same site on my other account, it loaded just fine. I've restarted my computer, restarted firefox, deleted cookies and caches and browser history, but still get the same message on my work account. Any idea how to fix this?

Thanks!

I was using firefox sync across multiple devices, but at some point in the past few months, i got locked out on one device due to too many wrong tries (i THINK. something went wrong anyway), and now, i am logged on on only 1 computer, and none of my passwords (even the one currently saved in my password manager, 1password) work when trying to log into other devices. using the QR scan from firefox/pair page on my ph doesn't work either. so, now i'm afraid of getting logged out from my main computer and then losing access to years worth of bookmarks & folders & plug-ins etc. unfortunately, when i went to try & add a back up email for my account, it was too late...it kept asking me to log in to do so, and my password isn't recognized anymore (or i maybe inadvertently changed w/ a typo inserted?). i was thinking about just trying to download all my bookmarks, deleting my current account, and creating a new one...but then i need the log in to delete the account. i want to keep the same email for the user name, since it's my main email.

i am at a loss as to how i can get around this impasse.

Embedded videos play on Safari but not Firefox. When I looked at the previous questions about this they were addressed in June 2012. Apparently it is happening again, at least in my case. Maybe it happened with the last upgrade, I don't know, but I never had this problem before. Would appreciate any input. I haven't changed any of my settings. Thanks.

Basically as the title says. The only sites this is an exception for is youtube as well as big streaming services but on youtube the video seems like it takes longer to buffer and has a lot more pauses.

I am on Version 117.0.1 which was installed on September 12th for me. I did not notice any issues prior.

I am on a macbook air which is updated to latest software.

I have tried the following:

Running it in troubleshoot mode. It did not fix the issue.

Turning on/off autoplay. It didn't work.

Clearing cookies/cache. Nothing.

Started firefox without a theme. Didn't do anything.

I unchecked "Use hardware acceleration when available." which did nothing.

Sites I have tried watching videos on include:

reddit

pornhub/other porn sites (for testing purposes...)

instagram

Vimeo

Olá. Já faz um tempo, mas meu web wpp não carrega mais nenhuma figurinha. Alguém conseguiu solucionar isso já? Ela fica como um arquivo de midia por baixar. Minha versão do ff é 117.0.1.

obg.

Firefox automatically updated on 18/09/2023. I now get the 'unable to connect' message for many bookmarked tabs (e.g. hotmail sign in). I have not changed any firefox settings and I can connect to the sites in Chrome. I'm running mac 10.15.7 Is this a bug or do I need to change a setting? Thanks in advance for help... Tim

I am told to disable pop-up blockers in order to have a payment verified. I do not know what pop-up blockers are, I do not know where they are. When I go to Settings and search for pop-up blockers, I am told "Sorry! There are no results in Settings for "pop-up blockers"; and instructed to visit Firefox Support. I have been sent on this circular quest three times now. Please help me.

Hi, I uninstalled my old firefox from macbook by going to the 'application' folder and dragging it into the bin I then installed a new firefox However now I have two firefox on my macbook - could anyone tell me how to solve this???

Thanks!

Hello Firefox Community,

I've been a long-time fan of Firefox's bookmarks management system, but over the past year, I've encountered a persistent issue that's affecting my productivity. I regularly use the bookmark bar and organize my bookmarks into folders. However, any changes I make don't seem to stick and get reset after a period of time. This is especially frustrating as I heavily rely on bookmarks to keep my browsing organized. Problem Details

Here's what typically happens:

1. I add a bookmark to a specific folder or position, either in the general list of bookmarks or on the bookmark toolbar.
2. Sometime later, that bookmark leaves its designated position and moves to the bottom of the unsorted list of bookmarks.

Devices and Operating Systems

• MacBook M1 2020 running macOS Monterey
• Dell Alienware 17 r5 running Windows 10

Both devices have the latest version of Firefox installed, and I use Firefox Sync to keep my bookmarks and settings consistent across these devices. Suspicion

I suspect that this issue occurs when I make a change to bookmarks on one computer and then open Firefox on the other computer. The bookmarks seem to reset, possibly due to some issue with Firefox Sync.

Looking forward to hearing your thoughts and possible solutions!

Kind regards,
