The name "Mozilla Firefox" is a registered trademark; along with the official Firefox logo, it may only be used under certain terms and conditions. Anyone may redistribute the official binaries in unmodified form and use the Firefox name and branding for such distribution, but restrictions are placed on distributions which modify the underlying source code.[80]
There has been some controversy over the Mozilla Foundation's intentions in stopping certain open source distributions from using the "Firefox" trademark. Former Mozilla CEO Mitchell Baker explained in an interview in 2007 that distributions could freely use the Firefox trademark if they did not modify source-code, and that the Mozilla Foundation's only concern was with users getting a consistent experience when they used "Firefox".[81]
To allow distributions of the code without using the official branding, the Firefox source code contains a "branding switch". This switch allows the code to be compiled without the official logo and name, for example to produce a derivative work unencumbered by restrictions on the Firefox trademark (this is also often used for alphas of future Firefox versions). In the unbranded compilation the trademarked logo and name are replaced with a freely distributable generic globe logo and the name of the release series from which the modified version was derived. The name "Deer Park" is used for derivatives of Firefox 1.5, "Bon Echo" for derivatives of Firefox 2.0, and "Gran Paradiso" is used for derivatives of Firefox 3.0. The codename Minefield and a modified version of the generic logo stylized to look like a bomb is used for unofficial builds of version 3.0 and later, and for nightly builds of the trunk.
Outside of certain exceptions made for "community editions", distributing modified versions of Firefox under the "Firefox" name requires explicit approval from Mozilla for the changes made to the underlying code, and requires the use of all of the official branding. For example, it is not permissible to use the name "Firefox" without also using the official logo. When the Debian project decided to stop using the official Firefox logo in 2006 (because of copyright restrictions on its use incompatible with the project's guidelines), they were told by a representative of the Mozilla Foundation that this was not acceptable, and were asked either to comply with the published trademark guidelines or cease using the "Firefox" name in their distribution.[82] Ultimately, Debian switched to branding their modified version of Firefox "Iceweasel", along with other Mozilla software.

In December 2005 Internet Week ran an article in which many readers reported high memory usage in Firefox 1.5.[109] Mozilla developers said that the higher memory use of Firefox 1.5 was at least partially due to the new fast backwards-and-forwards (FastBack) feature.[110] Other known causes of memory problems were malfunctioning extensions such as Google Toolbar and some older versions of Adblock,[111] or plug-ins, such as older versions of Adobe Acrobat Reader.[112] When PC Magazine compared memory usage of Firefox, Opera and Internet Explorer, they found that Firefox used approximately as much memory as the other two browsers.[113]
Softpedia also noted that Firefox 1.5 took longer to start up than other browsers,[114] which was confirmed by browser speed tests. IE 6 launches faster than Firefox 1.5 on Microsoft Windows since many of its components are built into Windows and are loaded during system startup. As a workaround for the issue, a preloader application was created that loads components of Firefox on startup, similar to Internet Explorer.[115] A Windows Vista feature called SuperFetch performs a similar task of preloading Firefox if it is used often enough.
Tests performed by PC World and Zimbra indicate that Firefox 2 uses less memory than Internet Explorer 7.[106][116] Firefox 3 uses less memory than Internet Explorer, Opera, Safari, and Firefox 2 in tests performed by Mozilla, CyberNet, and The Browser World.[117][118][119]
