I develop and maintain three addons for the Mozilla Firefox web-browser. The first, Modify Headers, allows the user to add, change and remove HTTP request headers. The second, XHTML Mobile Profile, renders content delivered using the Content-Type application/vnd.wap.xhtml+xml. The third and newest addon is Mailfrom and enables users to point mailto links to their favourite webmail client.
Just to let you know that the Mailfrom link above actually points to the Modify Headers page … !
Thanks for the pointer. The link has been fixed.
PS Thanks for your efforts – much appreciated!
Thank you for great add-ons! I am using both Modify Headers and XHTML-MP.
Could you please fix Bug 19056 and Bug 22002 (XHTML-MP)?
Hi wlkn, I’ll take a look at those defects and see what I can do. I’m really focusing on Modify Headers at the moment, but these defects look relatively straightforward:
About http://wap.mob.ua/ ;
They should have used & instead of & in the link. But shouldnt firefox just tolerate it ? Like it does with HTML?
Firefox should tolerate it. But the XSLT used by the XHTML Mobile Profile addon does not. I need to look at that again, as I think I can do the content processing without the use of XSLT. That change should improve tolerance of XML parsing errors.
Do you know where I can download sample headers to import into your add-on?
Hi Jenna, at present there are no sources of sample headers for import. However, I will be including sample headers in the next version of Modify Headers. To get started, I suggest searching Google for “HTTP headers tutorial”.
a bugfix release would be great (19056 & 22002)
Look for it soon.
Your Mailfrom addon is wonderful for Craigslist users! Before I found it, I noticed when I tried to respond to an ad it seems the mailto:firstname.lastname@example.org?subject=Emailsubject would populate all in the TO: field. Your addon has fixed this for me. I wonder if further customization would be available to allow users to choose whether what is included in the “subject” or “body” fields would be allowed to pass forward to the email client, in the options area. That would further enhance the end user experience I believe. Thanks all the same!!!
Hi Leo, I’m glad you like mailfrom. Some mail clients will accept the body of the message passed in. I’m not sure what that will take to implement. I’m focusing on Modify Headers at the moment, so please be patient until I get to it.
Hi Gareth, thanks for all the great addons. Is there a chance you’ll upgrade the mailfrom addon to the latest FF version in the near future? I really miss it…
Hi and many thanks for your work!
I was wondering if you consider upgrading Modify Header for FF 8 compatibility?
It is compatible up to version 9 as of today (Nov 28)
Hi, speaking about mailfrom, I have a question/suggestion.
Is this extension extended MAPI compliant? There are a lot of softwares that are using mail functions through extended mapi protocol and this requires outlook, since thunderbird isn’t mapi compliant.
I suppose that this limit is caused that many libraries (i.e. Delphi) have been developed with extended mapi in mind.
I suppose that with this function it would be a “killer extension”
I’m interested in finding out more about this idea, please file a ticket for an enhancement here: http://bit.ly/uUzHgT
have now installed on my windows7 pc w/firefox – thanks, now hoping soon I can use it on my android pad w/firefox – any chance that may hapen soon? thanks
I would like to develop a mobile version, but this requires a big investment in UI design as the mobile form factor makes entering long strings (such as User-Agent strings) difficult. I will come to it some time soon.
Hi, will we able to modify HTTP response headers in the next version? It feels like having the half of a program working if we can only modify request headers
I have been considering this feature. I’m not sure how effective it will be as some response header values will be used before the headers as passed to browser addons.
