I-Firefox Community Forum

I'm using the OneTab add-on, Enabled. The icon no longer shows on the Toolbar, though it is on the Menu bar next to Firefox View.

I ran Remove and then Added it again, hoping the Toolbar Icon would reappear = no go, And I lost all URLs already saved, stupid me. To be clear, clicking the Icon on the Toolbar saves all open tabs.

Is there a fix via Preferences? Thanks. gw

Contrast disappears when I klick 'Login' eg. on 'https://www.elektor.de/'; other browsers are ok. AdGuard on or off makes no difference. Kind Regards [removed email from public]

Secure connection cannot be established

When a website that requires a secure (HTTPS) connection tries to secure communication with your computer, Firefox cross-checks this attempt to make sure that the website certificate and the connection method are actually secure. If Firefox cannot establish a secure connection, it will display a Secure Connection Failed or Did Not Connect: Potential Security Issue error page. Secure Connection Failed

A Secure Connection Failed error page will include a description of the error and a Try Again button. There is no option to add a security exception to bypass this type of error.

I realize Facebook doesn't have a spell check feature,but is there a way my browser, Firefox, which I already have spell check enabled can somehow spell check Facebook when I chat? Can someone help? Thank you.

Firefox 115.12esr slow to startup takes up to 10 second to load the first time now Firefox was fine in version 112.esr. to bad Firefox forces updates, even when the update make Firefox worse. https://snipboard.io/QF0ERT.jpg of course it works faster without extensions, that does not mean anything. I would reinstall the older version but Mozilla fixed so we cannot. I do not have time to reinstall all the extension so I am left with a useless Firefox. To bad Firefox does not allow reinstall of extension automatically, a reset of Firefox would also make Firefox useless; I am at a loss to how to continue to support Mozilla and not switch to another browser?

I am trying to upload a document on the Supreme Court portal (UK) but it won't work I am told because my browser has to allow pop ups and cookies. Where can I get Firefox to so allow?

Because the economy, inflation, and lower incomes are still a major problem, many users like myself need to continue using old computers that can only run Windows 7. So we need Firefox ESR 115 to continue being supported with updates for at least a couple more years.

I've been a long time supporter of Firefox and it's taken me a few years get all the bugs out of Win 7 so I'm not going to repeat that on Win X. My Win7_64 water cooled platform is overclocked, stable, and just as fast as most affordable new chipsets from Intel. I have third party security apps and firewall. I'm not downgrading to Windows X whatever later version that is and I'm considering other browser options, if anybody has ideas?

Although I'm on the ESR channel, I've been using User Agent Switcher for a while, which seems to work well on most sites. I also notice DuckDuckgo browser claims to support Win 7. I will miss Firefox, but switching to a Win7 supported browser would be my first option, then Linux if I have to dump Windows 7 for something else.

Developers will moan and say switch to Win X with the favorite phrase 'Upgrade' when my experience has been the opposite, but what do others feel who are using older versions of Windows?

Deleting autofill entries does not work per article. The info is still there. Clearing history does not work either. Do I need to restart computer for it to forget/delete entries? Thank you. Fred couvrette

I have Firefox on two separate computers, a desktop running Win7Prof64bit and a laptop running Win10Pro 64bit. Both Firefox installations crash constantly, ie every 10 - 15 mins. They show the "Gah! Firefox just crashed. Please tell us what you were doing", and the box to return the data to Mozilla. With Restore This Tab at the bottom.

I always send you these reports but in about a year, the problem remains the same. Nothing has improved, I never hear back from you. Two different PCs, two different OSs, constant reports, no improvement. Why do I never hear from you? Why does this problem continue endlessly? I'm wasting my time sending you the reports. You take no notice. If you do, why does the problem continue and why do I never hear from you?

'Block Site' merely blocks access to a list of sites, but does not stop them appearing. is there a way to stop websites which use <gob.mx> in the address, which attempt to re-direct to 'mirror' sites that try to steal personal info and generate 'Illegal re-direct' warnings from anti-virus programs from appearing in firefox searches, automatically, rather than having to enter <XXXXXXX, -gob.mx> each time I search ?
