Diễn đàn hỗ trợ Firefox

I'm amazed, just AMAZED I can't find the answer to this with a simple google search, or searching the questions here, and I re-worded my search several times. All the answers I could find, even chatGPT (I know it's not alway sup to date) told me to use this option even though I specifically told it it wasn't there, is anyone aware that sometimes the option isn't there? What gives? Not blaming anyone specifically, but this a really simple question, I'm I the first person it's ever happened to?

I'm trying to fix a sound problem where videos will not play, and this is a suggested step. The sound on youtube videos plays with Google Chrome, so it's not my sound drivers, just with firefox it doesn't play. One of the steps as well was the clear my info, I cleared everything except history, I wished there was a way to back those up, I'll look it up.

Starting firefox in safe mode doesn't fix the problem either.

Good afternoon,

I've got a problem with add-ons while using Squid MITM Proxy with a custom certificate for Firefox/LibreWolf.

While I'm trying to update / install an extension / theme, it fails with:

``` 1686147276233 addons.xpi WARN Download of https://addons.mozilla.org/firefox/downloads/file/4104397/witchdoctor-2.0.xpi failed: [Exception... "Certificate issuer is not built-in." nsresult: "0x80004004 (NS_ERROR_ABORT)" location: "JS frame :: resource://gre/modules/CertUtils.sys.mjs :: checkCert :: line 177" data: no] Stack trace: checkCert()@resource://gre/modules/CertUtils.sys.mjs:177 onStopRequest()@resource://gre/modules/addons/XPIInstall.jsm:2514 ```

How can I install an add-on while using the MITM proxy?

I know there are ways , with more clicks or longer shortcuts to get to some folders but this is the main and most easily accessible way to get to my bookmarks. I know this has been discussed in some older posts but they are all archived so I can't ask any questions there. Sorting by name, for me, is quite inconvenient as sometimes the bookmarks title isn't immediately, easily remembered. Thanks.

I want to enable search suggestions, thus I enabled it from Settings >> Search >> Provide search suggestions (all 4 boxes are ticked). Furthermore, in about:config, I have the following parameters set to true:

• browser.search.suggest.enabled
• browser.urlbar.quicksuggest.allowPositionInSuggestions
• browser.urlbar.quicksuggest.enabled

I even downloaded the DDG extension, yet despite all that, nothing gets suggested. Just the history.

This is the case for many search engines I tried (DDG, startpage, Brave, SearXing).

Please let me know what I'm doing wrong, I've tried everything.

What is the code to remove that new menu Search Bookmarks in new firefox 114?

I already remove all the previous "bookmark all kind of type menu" in userchrome.css

I can't figure out what's gonna happen next with, I suspect, a new whiz bang deal w. The rule used to be something like: get new new button and one would magically appear - no questions, what kind, etc. The new stuff may be great for those starting out, I have used the same browser for, literally, years. I i'm not questioning that the new way is better, or worse, I am simply lazy and don't want to change my ways.

Thank you...............

Hi all Gurus,

I have been trying and searching but I could not find a suitable answer. Figured I try asking the question here.

Is there anyway or what is the policy that I can configure to disable the "New Tab Ctrl+T" function on the menu please? Attached image.
