Diễn đàn hỗ trợ Firefox

Is there a way to change the size of the sections in Firefox? For instance, I don't need so much space for the listings of Inbox, Sent etc. or the Tabs but would like to have more space for the web pages themselves. I ask because I've got a sight impediment and have to increase the text size. This means that the web "window" (Sorry, don't know the correct terminology) is so big that I have to scroll down to see it.

paypal is blocked on firefox .... why???? it was fine just a few days ago... but yesterday its blocked for security reasons??

the site is unsecure???

something is not right about this.

running mac os mojave firefox 115.29

I am receiving messages from my banks that my browser is no longer supported or that I should update my browser but my settings mean Firefox automatically updates. However, I cannot read PDF statements even though I have Adobe Acrobat Reader installed and, on further investigation, I see that Firefox no longer supports Adobe Reader. I am a fierce supporter of Firefox but does this mean I have to use another browser?

I sent message below to Bluesky support and have tried all their suggestions (all relating to Firefox), but to no avail.

MacBook Pro OS 10.14.6. Yesterday (9Dec2025) I could open Bluesky & see my profile but could not add a new post. I then did an ‘age verification’ and received confirming emails. When pressing ‘New Post’ button just went to blank page. Under ‘notifications’ at the top, was a message “''''! r.countGraphemes is not a function''''”. I am accessing using ‘Firefox 115.31.0esr (64-bit)’. I have deleted caches, re-started ‘Firefox’ and re-signed into Bluesky, but problem persists.

Could you please advise how I can overcome this problem. Thank you, best regards.
