I have been using Firefox for ages now, and collected a rather large number of bookmarks (>15,000) As far as I know such a number poses some issues, for instance I tried several times to use Sync but was never able to use it.

Since I am using two different machines, I tend to save my bookmarks only on the main one. When I am working on the laptop I never save bookmarks but I message them to myself (never been able to save them on my main machine, sigh) and every once in a while I "restore" bookmarks from the backup set of the main machine on the laptop. It always takes a while and oftentimes it feels like the process hangs, but so far I managed.

Today I started wondering again if there's a less frustrating and more efficient way to handle this. The question I started asking myself was: could I use the same FF profile from the laptop & the main machine? Say by saving it in the cloud?

Thanks for any hint or suggestion!

Hey All,

I've seen a few instances of SSL_ERROR_UNSUPPORTED_HASH_ALGORITHM since the last update.

https://www.loot.co.za/ is one notable example. The same site opens fine on Chromium 87.

I've been looking around but have not been able to find what's causing it, it's not even mentioned in the documentation.

So far I've tried switching right down to TLS 1.1 via flags to no avail.

OS: Fedora 33 Workstation Firefox: 84.0.1 (64-bit)

Any ideas?

I am attempting to change my secondary email address with the intent to make my new email the primary email. I have removed the old secondary email, but when I try to add the email address that I want. I get an error message saying that the email already exists. I note that in the Firefox account dialog the secondary email address is blank.

I did sign up for Firefox VPN using the email address that I'd like to use and so that's a possible reason. I just don't know how to fix it. Note; I'm no longer planning to use Firefox VPN. I wonder if perhaps there's a way to cancel/delete that account.

Yours Not the sharpest tool. (I feel like I'm not the sharpest fool.)

I'm working on an addon to automate taking screenshots of lecture slides. I'm using a canvas object to capture and save the file blobs and JSZip to zip everything together and download. But JSZip keeps throuhing the `unsupported file type` error. Even though blobs are supported.

Here's the relevant code I'm using Github File

I've submitted an issue to the maintainer which has some more debugging info. The script in the addon_context has some very quantum behaviour and changes output every time I console.log Github Issue

I'm wondering if there might be a problem on my end, with the way I'm generating and processing the blobs. The same code works in chromium based browser, I'm confused as to what Firefox does differently. Any help would be appreciated.

Hello, the problem with Firefox is that it loads the pages too slow, other browsers such as Chrome or Opera are working correctly. At first everything was fine but suddenly Firefox started to take forever to load the pages. I have completely uninstalled Firefox and installed it again but the problem persists. I thought it was a problem with some extension (I only use AdBlocker and HttpsEverywhere) but restarting it in safe mode the problem persists. I also have to mention that the Ubuntu installation is recent. What could be the problem?. I am using Ubuntu 18.04.5 LTS.

This all started after last firefox upgrade/update a few weeks ago so installed gmail chrome which works fine.

Even reistalled OS & then worked ok till firefox did it’s own updae.

I have deleted & reinstalled a couple of times but same problem.

I use Linux Ubuntu 20.04.2LTS on an older (+/- 5 year) HP Pro 3130 MT a 64 bit machine. Chuck

Hi i would like to know how i can change the font size of my Firefox Menu.

i already change the size of the layout whit "layout.css.devPixelsPerPx" but it didn´t change the font size of the tabs or the menu. i did some research and found the userCrome.css technique to change some fonts sizes. i already change the font size of the address bar, PopMenu and tabs. But when it comes to the Main Menu, and bookmarks the font still in the same size. i also try changing the fonts size on preferences but nothing has been working.

i guess there must be a simple command line to add in the userCrome.css file to fix this but i can find it.

if some of you can help me i will appreciate very much.

i am working on a linux machine. thank you very much

Hello everyone,

I'm an avid user of Firefox latest on Manjaro, up to date.

Since yesterday, when I updated from Firefox 87.0-1 to 87.0-2, I have a strange bug using DuckduckGo.

What happens ?

• When on DuckduckGo result page, clicking a link won't open when using the "Open in another tab" setting
• I will open the link if that setting is not used
• I can open it in a new tab with the right-click menu, or by ctrl-clicking it.
• When hovering above a link, the bottom-left tooltip does show up and the cursor does become a hand, suggesting the link should work. Alas, it doesn't.

What did I try ?

• I did restart in "safe mode", with all addons disabled.
• I did reset the cache.
• I tried testing the same behavior on Google, and it did work as expected.
• I tried DDG in another browser (Gnome Web/Epiphany), and it worked as expected.

I have yet to notice the same issue with any other website. Any Idea where I should report this minor, but annoying but ?

Thanks & Cheers, -- JAB

Hello everybody,

There are more and more websites that have functions that no longer work with Firefox and force me to use Chromium instead. Do you if there is any chance that an upcoming release will put everything right?

Thank you in advance Virginie

[[This old answer|https://support.mozilla.org/en-US/questions/1219521]] describes on how to get it back .. though for me there is no "Add to Address Bar" button.

Using Firefox 78.9.0esr (64-bit) (Default firefox from debian bullseye)

Firefox ESR : video in supported format and MIME-type was not found. https://vsx.mpchat.com/data/tmp/chat_161847892912.ogg This is a systematic problem with this browser. In other browsers, this AUDIO is played without problems! Dan

The default Amazon search that comes built-in with Firefox points to Amazon.com. Is there a way to search for other marketplaces, like amazon.com.au or amazon.sg ?

Hello,

 When receiving a message, Thunderbird considers a line containing "--" to be a signature start mark and automatically removes all following lines (instead of quoting it) when editing the reply. 

I want to disable this behavior. (The content of my (reply) message is my responsibility, I dislike automation on my authoring. ;-) )

So, how to configure this?

Regards.

when trying to open google

I had a system update couple of days ago and since then, the firefox browser suddenly hangs or partially blacks out in certain areas suddenly. It sometimes corrupts the text/data on the toolbars, add-ons, etc.

It happens randomly. When I restart the system it works fine and then it happens again at random instance.

Not sure what is causing this. But this only began since Thursday.

Not sure what to do.

My ISP is Plusnet. When I try to access their website using Firefox browser I get the following error:

=====

Secure Connection Failed

An error occurred during a connection to webmail.plus.net. Cannot communicate securely with peer: no common encryption algorithm(s).

Error code: SSL_ERROR_NO_CYPHER_OVERLAP

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the web site owners to inform them of this problem.

I have reported the problem to Plusnet but they say 'not our problem'. Their reason being that the problem does not occur using Google Chrome.

Can you help please?

Where are the site proprietary ? ;-) Firefox 87.0 (64 bits) in Debian Sid

Starting today, on Firefox 87.0 for Linux, any link that I had visited in the past is showing up as visited in the current session. I am in the process of updating thousands of listings on Ebay and the link color helps me keep track of where I am in the list each day, especially since I have had to start back from the beginning of the list 3 times. I do not want to clear my history as I keep going back to it to reference old pages. Is there a setting to clear the links visited color without clearing the history? Or is this a bug?
