Firefox Portable

hello, i'm using Firefox Portable 74.0 (64-bit), the latest version from the download site, downloaded through the portableapps platform app. i have discovered that i cannot clear the browsing history no matter what i do. i'm not sure when this started, but historically it has worked just fine.

I have ESET installed and https filter option on.
When i use firefox it shows an error on every website:

Secure Connection Failed
An error occurred during a connection to www.xxx.com. PR_END_OF_FILE_ERROR

I've tried turn https filter option off and on. And imported the filter certificate of ESET to firefox but still dont work.
Does someone know how to solve this? Thanks

I put firefox portable in D:\internet folder and put a FirefoxPortable.ini in the same folder as FirefoxPortable.exe:
[FirefoxPortable]
FirefoxDirectory=App\firefox
ProfileDirectory=Data\profile
SettingsDirectory=Data\settings
PluginsDirectory=Data\plugins
FirefoxExecutable=firefox.exe
AdditionalParameters=
LocalHomepage=
DisableSplashScreen=false
AllowMultipleInstances=false
DisableIntelligentStart=false
SkipCompregFix=false
RunLocally=false

Has anyone else have an issue with the latest iteration (73.0.0 and 73.0.1) not being able to
1. open certain webpages (Chrome and IE11 work)
2. download files (it keeps failing on everysite)
Thank you
Update: I'm running Windows 7 x64
Proxy is set to NONE
Privacy is STANDARD
I'm getting the following on one sites download "page"
"Error code 20

The proxy failed to connect to the web server, due to TCP connection timeout.

Hello,

Hi all - being a newbie to this Forum, I'm hoping you more experienced users will be able to advise me.

I had Firefox Portable ver 59 working just fine, when suddenly it got updated to ver 72, then 73. This is in spite of me having turned off automatic updates ! I've followed various tips & tricks on the 'Net, but nothing seems to stop it happening. I'd welcome any advice on any more settings that I can change.

Its size is 177kb so its not a shortcut. Its in the first folder of FirefoxPortable yet there's a folder called App which holds both the 32 and 64 bit versions. When I used this FirefoxPortable.exe it opened the 32 bit version even though I have a 64 bit system. Shouldn't it have defaulted to the 64 bit version?

When I click on a link http or https Firefox opens a new instance or I want it to open the link in a new tab

I did check the "open in a new tab rather than a window" box.

These show up when Im in the browser, no issue, but they refuse to make any sound (in any situation) or show up when Im in another app in windowed fullscreen.

Is there any workaround/solution for this? I would hate to have to run another browser as well, but I really need the notifications to work properly (I have several tabs that notify me of information that I need in a timely fashion).

Under App there is
Firefox
Firefox64

If I downloaded the 64 bit version why is the 32 bit version here? Can I delete it safely? If one uses a 64 bit system why would anyone want a 32 bit program running if there was a 64 bit one available?

I had to go into Control Panel, Default Programs and switch change a lot of the programs that were still using the 32 bit program. Took quite a while.
